Technical highlights
All-discrete topology.
Single-pass, series regulator design.
No
IC (integrated circuits) are used. This allows complete design control
over all operating points and parameters for superior performance.
Low noise, high PSRR
A
constant-current source feeds a zener diode as a stable voltage
reference. A low-pass filter (with a corner frequency of 1.6Hz) prevents
zener noise from being introduced into the error amplifier. This is an
effective yet lower-cost alternative to expensive voltage reference ICs.
The low-pass filter also provides a soft-start characteristic.
The
output noise (unloaded) is less than 13µV at 24VDC output (measured
using a Tangent LNMP (low-noise measurement preamplifier) and a Fluke
187 50000-count DMM in ACmV mode). The output noise is even less when
the output voltage is lower. This is much better than the noise of an IC
regulator based PSU tested under identical conditions.
The error
amplifier is a discrete implementation of an opamp with a high open-loop
gain of 102.5dB. The voltage supply to the error amplifier is isolated
with capacitance multipliers to boost its PSRR (power supply rejection
ratio). This greatly improves the line regulation performance of the
PSU.
A long-tailed pair differential amplifier with current mirror
and constant current source forms the first stage of the error
amplifier. The second stage is the voltage amplification stage (VAS),
also with constant current source load. The 3rd stage is comprised of
the power MOSFET output devices configured as a source follower.
