In an operational amplifier v- is on bin number 4

In an operational amplifier The differential input voltage vd is given by

In an operational amplifier… is the voltage between the inverting terminal and gro

Vo = Avd =

is called the open-loop voltage gain because it is the gain of the op amp without any external feedback from output to input

An op amp is ideal if it has

In ideal op amp v1 != v2

In ideal op amp v2 – v1 = …

reverses the polarity of the input signal while amplifying it.

Vo

i1 = i2

circuit is

i1 = i2

Vo

Av = vo/vi =

amplifier is an op amp circuit designed to provide a positive voltage gain.

Under these conditions (Rf =0 and R1 =∞), the circuit is called …
