Question

The phase in the integrator and differentiator circuit respectively are

(a) +90 degrees and +90 degrees

(b) -90 degrees and -90 degrees

(c) -90 degrees and +90 degrees

(d) +90 degrees and -90 degrees

This question was posed to me during a job interview.

Origin of the question is Integrators and Differentiators topic in section Operational Amplifiers of Electronic Devices & Circuits

Answer 1

The correct choice is (d) +90 degrees and -90 degrees

The best I can explain: These are the characteristics of the integrators and differentiators circuits respectively.
