asked Nov 16, 2023 in Linear Integrated Circuits by Julian (38.2k points)

What will be the absolute value of phase shift, if the frequency keeps increasing?

(a) Increase towards 45^o

(b) Decrease towards 45^o

(c) Increase towards 90^o

(d) Decrease towards 90^o

This question was addressed to me during an interview for a job.

My query is from Open-Loop Voltage Gain as a Function of Frequency topic in portion Practical Limitations of Op Amp Circuits of Linear Integrated Circuits

answered Jan 15 by Chris (39.8k points)

Right answer is (c) Increase towards 90^o

Unravel the mysteries with: For any frequency above break frequency, the absolute value of phase shift increases towards 90^o with increase in frequency.
