where GBWP
U1
is the Gain-Bandwidth Product of
U1. As R
3
is made larger, f
UG
becomes smaller. f
UG
should be large enough so that U2’s 1/f noise does not
significantly impact the output noise.
Adjust R
7
so that the gain at f << f
UG
matches the gain at
f >> f
UG
.
Precision Half-Wave Rectifier
Figure 8 shows a precision half-wave rectifier. When
V
in
> 0, D
1
is on and D
2
is off. When V
in
< 0, D
1
is off and
D
2
is on. The second amplifier (U2) buffers V
o
from the
variable output impedance of the rectifier.
The output voltage is:
Figure 8: Precision Half-Wave Rectifier
Diodes D
1
and D
2
need to be Schottky or PIN diodes to
minimize delay.
Set R
2
= R
3
to the recommended feedback resistor value
for the gain A
v
= -R
2
/R
1
. R
2
and R
3
may need to be
increased slightly to compensate for the delays through
D
1
and D
2
.
Set R
6
to the recommended feedback resistor value for
the gain A
v
= (1 + R
6
/R
5
).
R
4
is an optional resistor; it helps isolate U2’s input from
the changing output impedance of U1.
Other configurations are possible:
1) Connect U2’s input between R
3
and D
2
so that
V
o
≠
0 for V
in
< 0.
2) Use an inverting gain configuration for U2 to
change the polarity of V
o
.
Pick the combination that best suits your needs.
