The best method to eliminate output error and minimize thermal drift of an op amp is by
A) connecting a compensating capacitor.
B) using a nulling circuit.
C) using a tuned amplifier.
D) using a RLC filter.

Question

Quizplus · Accepted Answer

Using a nulling circuit is the best method to eliminate output error and minimize thermal drift of an op amp. A nulling circuit consists of a potentiometer that allows adjusting the input offset voltage of an op amp to zero. This nulling process compensates for any offset voltage that may be caused by errors in the manufacturing process, temperature changes, or aging. A compensating capacitor can help reduce noise but will not address any offset voltage errors. A tuned amplifier and RLC filter are not related to eliminating output error and minimizing thermal drift.
