Review: Op Amp Circuit Analysis
Procedure
:
1. Assume that the op amp is ideal
a) Apply KCL at (+) and (–) terminals, noting
i
p
= 0 &
i
n
= 0
b) Note that
v
n
=
v
p
c) Write an expression for
v
o
2. Calculate
v
o
3. Check: Is the opamp operating in its linear region?
If
V
–
≤
v
o
≤
V
+
,
,
then the assumption is valid.
If calculated
v
o
>
V
+
, then
v
o
is saturated at
V
+
If calculated
v
o
<
V
–
, then
v
o
is saturated at
V
