Paul Rako Electronic Design Using a bootstrapping scheme with a JFET can enhance a photodiode’s ac response, but adds unwanted dc voltage. Remedy that problem with a matched dual-JFET. Linear Technology has a good application note [1] about ...

Abhirup Lahiri Electronic Design Inductors designed with active elements are very desirable to designers today because conventional spiral inductors are too big, too heavy, and too costly, and they require tuning. During the last few decades, ...

Chau Tran and Paul Mullins, Analog Devices EDN You sometimes need to measure load currents as large as 5 A in the presence of a common-mode voltage as high as 500 V. To do so, you can use Analog Devices’ AD8212 high-voltage current-shunt ...

Moshe Gerstanhaber EDN State-of-the-art ADCs accept differential inputs, allowing you to differentially implement the entire signal path from sensor to converter. This structure provides significant performance advantages, because differential ...

Chuck Wojslaw EDN Figure 1. This schematic depicts a basic voltage-to-frequency converter. The basic VFC (voltage-to-frequency converter) in Figure 1 comprises an integrator (IC 1 ) and a Schmitt-trigger circuit (IC 2 ). The integrator converts the ...

Robert Most EDN Circuits that latch one-of-N switches usually use a digital approach. Such circuits are often useful in human-interface situations, such as audio-mixing consoles, video-feed selection, or current-loop-control redundancy systems. In ...

John Guy, Maxim Integrated Products EDN Advances in semiconductor technology have allowed ICs to replace many mechanical relays, but relays still dominate in high-current circuits that must stand off high voltages of arbitrary polarity. Contact ...

Dave Conrad EDN There have been many different ideas presented for increasing the acoustic output of a piezo buzzer or ultrasonic transducer. Most of them involve rather complicated circuitry that drives up the total solution cost; such as boosting ...

Giovanni Romeo EDN Controlling a power supply is a necessary task in many applications, such as in battery chargers, solar power controllers, and so on. Industry provides a rich number of off-the-shelf integrated power supplies that, unfortunately, ...
