Transistor & OPAMP Crossword

Type
Crossword
Description

A differential amplifier is a part of an Op-amp
In the common mode an identical signal appears in i/ps
The common-mode gain is very low
The differential gain is very high
If Vin is 0, Vo is zero
The use of negative feedback reduces the voltage gain
Negative feedback increases the Zin and B.W
A voltage follower has voltage gain of 1
Op-amp can amplify both a.c. and d.c.
The input offset current equals difference between base currents
The tail current in a differential amplifier equals sum of two emitter currents
A common-mode signal is applied to both iputs
The input stage of an Op-amp is usually a differential amplifier
Current cannot flow to ground through a virtual ground
