4.0 Phase Inverting AC Amplifier
A single supply phase inverting AC amplifier is shown in Fig-
ure 2 The output voltage is biased at mid-supply, and AC in-
put signal is amplified by (R
/R
). Capacitor C
acts as an
input AC coupling capacitor to block DC potentials. A capaci-
tor of 0.1μF or larger can be used. The output of the LMV111
can swing rail-to-rail. To avoid output distortion, the
peak-to-peak amplitude of the inputAC signal should be less
than V
CC
(R
1
/R
2
).
It is recommended that a small-valued capacitor is used
across the feedback resistor R
to eliminate stability prob-
lems, prevent peaking of the response, and limit the band-
width of the circuit. This can also help to reduce high fre-
quency noise and some other interference.
5.0 Fixed Current Source
A multiple fixed current source is show in Figure 3 A refer-
ence voltage (V
= 2.5V) is established across resistor R
3
by the voltage divider (R
and R
). Negative feedback is
used to cause the voltage drop across R
to be equal to
V
. This controls the emitter current of transistor Q1 and if
we neglect the base current of Q1 and Q2, essentially this
same current is available out of the collector of Q1. A Dar-
lington connection can be used to reduce errors due to the
bias current of Q1.
6.0 Difference Amplifier
The difference amplifier allows the subtraction of two volt-
ages or, as a special case, the cancellation of a signal com-
mon to two inputs. It is useful as a computational amplifier, in
making a differential to single-ended conversion or in reject-
ing a common mode signal.
