An engineer is testing an amplifier circuit For a low freque

An engineer is testing an amplifier circuit. For a low frequency square wave input signal, the output is similar to a square wave except that it has 30% overshoot and it has damped oscillation/ringing at 200 kHz. What does the response indicate? Comment on the change in the amplifier\'s performance if the amplifier\'s gain is reduced.

Solution

a) response indicate underdamped

b) if the gain of ampifier is reduce then bandwidth will increase as gain bandwidth product is constant
