Question

Consider a symmetrical square wave of 20-V peak-to-peak, 0 average, and 2-ms period applied to a Miller integrator. Find the value of the time constant CR such that the triangular waveform at the output has a 20-V peak-to-peak amplitude.

(a) 0.25ms

(b) 0.50ms

(c) 2.5ms

(d) 5.0ms

The question was asked at a job interview.

The above asked question is from Integrators and Differentiators topic in section Operational Amplifiers of Electronic Devices & Circuits

Answer 1

Right option is (b) 0.50ms

To explain: According to the question 1/CR = 2.
