Single-Supply Half-Wave and Full-Wave Rectifiers
An AD823 configured as a unity gain follower and operated
with a single supply can be used as a simple half-wave rectifier.
The AD823’s inputs maintain picoamp level input currents even
when driven well below the minus supply. The rectifier puts that
behavior to good use, maintaining an input impedance of over
10
11
for input voltages from 1 volt from the positive supply to
20 volts below the negative supply.
The full- and half-wave rectifier shown in Figure 43 operates as
follows: when V
IN
is above ground, R1 is bootstrapped through
the unity gain follower A1 and the loop of amplifier A2. This
forces the inputs of A2 to be equal, thus no current flows
through R1 or R2, and the circuit output tracks the input. When
V
IN
is below ground, the output of A1 is forced to ground. The
noninverting input of amplifier A2 sees the ground level output
of A1, therefore, A2 operates as a unity gain inverter. The out-
put at node C is then a full-wave rectified version of the input.
Node B is a buffered half-wave rectified version of the input.
Input voltage supply to
±
18 volts can be rectified, depending on
the voltage supply used.
