Question

The offset voltage in the voltage follower is balanced using

(a) Voltage drop across the load resistor

(b) Voltage drop across feedback resistor

(c) Compensating network connected to inverting input terminal

(d) Compensating network connected to non- inverting input terminal

I got this question in unit test.

Enquiry is from Input Offset Voltage in chapter Operational Amplifier Fundamentals of Linear Integrated Circuits

Answer 1

Accurate answer is (b) Voltage drop across feedback resistor

Expand on the concept with: Voltage drop across the feedback resistor connect to inverting input terminal is used to cancel the offset voltage in voltage follower.
