Measuring 2nV/в€љHz Noise and 120dB Supply Rejection
on Linear Regulators
The Quest for Quiet
Todd Owen and Amit Patel
Introduction MEASURING OUTPUT VOLTAGE NOISE A quiet, well regulated supply is important for optimum
performance with a number of circuit applications. Voltage controlled oscillators (VCOs) and precision voltage
controlled crystal oscillators (VCXOs) respond to small
changes in their supply very quickly. Phase-locked loops
(PLLs) require a stable supply as signal on the supply
translates directly to phase noise in the output. RF amplifiers require quiet supplies as they have little to no ability
to reject supply variations and regulator variation will
appear as unwanted side bands and lower the signal-tonoise ratio. Low noise amplifiers and analog-to-digital
converters (ADCs) do not have infinite supply rejection
and the cleaner the regulator output is, the higher their
performance. These are just a few applications where linear
regulators are required to provide quiet power supply rails,
but how does one ensure that the regulator is performing
as advertised? Being Quiet is Nothing New Once fully built, one can determine if the supply being
used has low enough noise for the application. Oscillator
phase noise is measured and compared against results
achieved with a known good supply, ADCs are checked …

DC/DC converter 25 When it comes to powering noise-sensitive analog/RF applications,
low dropout (LDO) linear regulators are generally preferred over their
switching counterparts. Low noise LDOs power a wide range of
analog/RF designs, including frequency synthesizers (PLLs/VCOs),
RF mixers and modulators, high speed and high resolution data
converters (ADCs and DACs) and precision sensors. Nevertheless,
these applications have reached capabilities and sensitivities
that are testing the limits of conventional low noise LDOs.
For instance, in many high end VCOs, power supply noise
directly affects the VCO output phase noise (jitter). Moreover,
to meet overall system efficiency requirements, the LDO
usually post-regulates the output of a relatively noisy …
