    Designing Linear Circuits for 5V Single Supply Operation
    Jim Williams
    In predominantly digital systems it is often necessary
    to include linear circuit functions. Traditionally, separate
    power supplies have been used to run the linear components (see Box, “Linear Power Supplies—Past, Present,
    and Future”).
    Recently, there has been increasing interest in powering
    linear circuits directly from the 5V logic rail. The logic
    rail is a difficult place for analog components to function.
    The high amplitude broadband current and voltage noise
    generated by logic clocking makes analog circuit operation difficult. (See Box, “Using Logic Supplies for Linear
    Functions”.)
    Generally speaking, analog circuitry which must achieve
    very high performance levels should be driven from dedicated supplies. The difficulties encountered in maintaining
    the lowest possible levels of noise and drift in an analog
    system are challenging enough without contending with
    a digitally corrupted power supply.
    Many analog applications, however, can be successfully
    implemented using the logic supply. Combining components intended to provide high performance from the 167Ω Q1 –

    Designs for High Performance Voltage-to-Frequency
    Converters
    Jim Williams
    Monolithic, modular and hybrid technologies have been
    used to implement voltage-to-frequency converters. A
    number of types are commercially available and overall
    performance is adequate to meet many requirements. In
    many cases, however, very high performance or special
    characteristics are required and available units will not work.
    In these instances V→F circuits specifically optimized for
    the desired parameters(s) are required. This application
    note presents examples of circuits which offer substantially improved performance over commercially available
    V→Fs. Various approaches (see Box Section, “V→F
    Design Techniques”) permit improvements in speed, dynamic range, stability and linearity. Other circuits feature
    low voltage operation, sine wave output and deliberate
    nonlinear transfer functions.
    Ultra-High Speed 1Hz to 100MHz V→F Converter
    Figure 1’s circuit uses a variety of circuit methods to
    achieve wider dynamic range and higher speed than any
    commercial V→F. Rocketing along at 100MHz full-scale

    Unique IC Buffer Enhances Op Amp Designs,
    Tames Fast Amplifiers
    Robert J. Widlar
    Abstract: A unity gain IC power buffer that uses NPN
    output transistors while avoiding the usual problems of
    quasi-complementary designs is described. Free of parasitic oscillations and stable with large capacitive loads, the
    buffer has a 20MHz bandwidth, a 100V/Ојs slew and can
    drive В±10V into a 75О© load. Standby current is 5mA. A
    number of applications using the buffer are detailed, and
    it is shown that a buffer has many uses beyond driving
    a heavy load.
    Introduction
    An output buffer can do much more than increase the
    output swing of an op amp. It can also eliminate ringing
    with large capacitive loads. Fast buffers can improve the
    performance of high speed followers, integrators and
    sample/hold circuits, while at the same time making them
    much easier to work with.
    Interest in buffers has been low because a reasonably
    priced, high performance, general purpose part has not
    been available. Ideally, a buffer should be fast, have no ...

    Composite Amplifiers
    Applications often require an amplifier that has extremely high performance in several areas. For example, high speed and DC precision are often needed. If a single device cannot simultaneously achieve the desired characteristics, a composite amplifier made up of two (or more) devices can be configured to do the job. AN21 shows examples of composite approaches in designs combining speed, precision, low noise and high power.

    Composite Amplifiers
    Jim Williams
    Amplifier design, regardless of the technology utilized, is
    a study in compromise. Device limitations make it difficult
    for a particular amplifier to achieve optimal speed, drift,
    bias current, noise and power output specifications. As
    such, various amplifier families emphasizing one or more
    of these areas have evolved. Some amplifiers are very good
    attempts at doing everything well, but the best achievable
    performance п¬Ѓgures are limited to dedicated designs. designed with little attention to DC biasing considerations
    if a separate stabilizing stage is employed.
    Figure 1 shows a composite made up of an LTВ®1012 low drift
    device and an LT1022 high speed amplifier. The overall circuit is a unity-gain inverter, with the summing node located
    at the junction of three 10k resistors. The LT1012 monitors
    this summing node, compares it to ground and drives the
    LT1022’s positive input, completing a DC stabilizing loop
    around the LT1022. The 10k-300pF time constant at the
    LT1012 limits its response to low frequency signals. The
    LT1022 handles high frequency inputs while the LT1012
    stabilizes the DC operating point. The 4.7k-220О© divider
    at the LT1022 prevents excessive input overdrive during ...

    Thermocouple Measurement
    Jim Williams
    Introduction Thermocouples in Perspective In 1822, Thomas Seebeck, an Estonian physician, accidentally joined semicircular pieces of bismuth and copper
    (Figure 1) while studying thermal effects on galvanic arrangements. A nearby compass indicated a magnetic disturbance. Seebeck experimented repeatedly with different
    metal combinations at various temperatures, noting relative
    magnetic п¬Ѓeld strengths. Curiously, he did not believe that
    electric current was flowing, and preferred to describe the
    effect as “thermo-magnetism.” He published his results in
    a paper, “Magnetische Polarisation der Metalle und Erze
    durch Temperatur-Differenz” (see references). Temperature is easily the most commonly measured
    physical parameter. A number of transducers serve temperature measuring needs and each has advantages and
    considerations. Before discussing thermocouple-based
    measurement it is worthwhile putting these sensors in
    perspective. Figure 2’s chart shows some common contact
    temperature sensors and lists characteristics. Study reveals
    thermocouple strengths and weaknesses compared to
    other sensors. In general, thermocouples are inexpensive,
    wide range sensors. Their small size makes them fast and
    their low output impedance is a benefit. The inherent voltage output eliminates the need for excitation. Subsequent investigation has shown the “Seebeck Effect”
    to be fundamentally electrical in nature, repeatable, and
    quite useful. Thermocouples, by far the most common ...

    Applications for a Switched-Capacitor Instrumentation
    Building Block
    Jim Williams
    CMOS analog IC design is largely based on manipulation
    of charge. Switches and capacitors are the elements used
    to control and distribute the charge. Monolithic п¬Ѓlters, data
    converters and voltage converters rely on the excellent
    characteristics of IC CMOS switches. Because of the importance of switches in their circuits, CMOS designers have
    developed techniques to minimize switch induced errors,
    particularly those associated with stray capacitance and
    switch timing. Until now, these techniques have been used
    only in the internal construction of monolithic devices. A
    new device, the LTCВ®1043, makes these switches available
    for board-level use. Multi-pole switching and a self-driven,
    non-overlapping clock allow the device to be used in circuits
    which are impractical with other switches. Conceptually, the LTC1043 is simple. Figure 1 details its
    features. The oscillator, free-running at 200kHz, drives a
    non-overlapping clock. Placing a capacitor from Pin 16 to
    ground shifts the oscillator frequency downward to any
    desired point. The pin may also be driven from an external
    source, synchronizing the switches to external circuitry. ...

    Some Techniques for Direct Digitization of Transducer Outputs
    Jim Williams
    Almost all transducers produce low level signals. Normally,
    high accuracy signal conditioning amplifiers are used to
    boost these outputs to levels which can easily drive cables,
    additional circuitry, or data converters. This practice raises
    the signal processing range well above the error floor,
    permitting high resolution over a wide dynamic range.
    Some emerging trends in transducer-based systems are
    causing the use of signal conditioning amplifiers to be
    reevaluated. While these amplifiers will always be useful,
    their utilization may not be as universal as it once was.
    In particular, many industrial transducer-fed systems are
    employing digital transmission of signals to eliminate
    noise-induced inaccuracies in long cable runs. Additionally, the increasing digital content of systems, along with
    pressures on board space and cost, make it desirable to
    digitize transducer outputs as far forward in the signal chain
    as possible. These trends point toward direct digitization
    of transducer outputs—a difficult task.
    Classical A/D conversion techniques emphasize high level
    input ranges. This allows LSB step size to be as large ...

    Application Considerations and Circuits for a New
    Chopper-Stabilized Op Amp
    Jim Williams
    A great deal of progress has been made in op amp DC
    characteristics. Carefully executed designs currently available provide sub-microvolt VOS О”T drift, low bias currents
    and open-loop gains exceeding one million. Considerable
    design and processing advances were required to achieve
    these specifications. Because of this, it is interesting to
    note that amplifiers with even better DC specification
    were available in 1963 (Philbrick Researches Model
    SP656). Although these modular amplifiers were large
    and expensive (≈3" × 2" × 1.5" at $195.00 1963 dollars)
    by modern standards, their DC performance anticipated
    today’s best monolithic amplifiers while using relatively
    primitive components. This was accomplished by employing chopper-stabilization techniques (see Box “Choppers,
    Chopper-Stabilization and the LTC®1052”) instead of the
    more common DC-differential stage approach.
    The chopper-stabilized approach, developed by E. A.
    Goldberg in 1948, uses the amplifier’s input to amplitude
    modulate an AC carrier. This carrier, amplified and synchronously demodulated back to DC, furnishes the amplifier’s PARAMETER
    EOS – 25°C ...
