should be large enough so that U2’s 1/f noise does not

significantly impact the output noise.

Set R = R to the recommended feedback resistor value

for the gain A = -R /R . R and R may need to be

Adjust R so that the gain at f << f matches the gain at

Precision Half-Wave Rectifier

Figure 8 shows a precision half-wave rectifier. When

V > 0, D is on and D is off. When V < 0, D is off and

Set R to the recommended feedback resistor value for

the gain A = (1 + R /R ).

R is an optional resistor; it helps isolate U2’s input from

D is on. The second amplifier (U2) buffers V from the

The output voltage is:

Other configurations are possible:

1) Connect U2’s input between R and D so that

V ≠ 0 for V < 0.
