Question

Which factor makes the differentiator circuit unstable?



a.Output impedance



b.Input voltage



c.Noise



d.Gain?

Answer 1

I think the answer is input voltage..............but not sure

HOPE IT IS CORRECT:)

Answer 2

Option D is the answer

Gain:

Explanation: The gain of the differentiator circuit (RF / XC1) increases at a rate of 20dB/decade as the frequency increases. As a result, the circuit becomes unstable.

Applications:

• A differentiator, in ideal conditions, reverses the effects of an integrator on a waveform, and vice versa.
• As a result, they're frequently utilised in wave-shaping circuits to detect high-frequency components in input signals.
• Differentiators are essential components of electronic analogue computers and PID controllers.
