The Input Offset Current Equals the__.

By Mohit Uniyal|Updated : July 4th, 2022

The input offset current equals the________.

A. average of two base currents
B. collector current divided by the current gain
C. difference between two base-emitter voltages
D. difference between two base currents.

The input offset current equals the difference between two base currents.

Solution:

Input offset current: It is not necessary that IB+and IB- are the same. Their difference is known as input offset current and generally the order of 200nA for BJT and 10pA for FET and the output in the absence of input will be

Vout=RF.(IOS) order of mV

Where     IOS=   IB+-IB-

This effect of Input offset current can be minimized by using the value of RF.

Therefore, The input offset current equals the difference between two base currents.

Hence, Option (D) is the correct answer.
