Question 109easy
The gain of an RF amplifier with a tuned LC circuit for the collector is maximum at the resonant frequency because of
Question 110easy
An op-amp has an open-loop gain of 105 and an open-loop upper cutoff frequency of 10 Hz. If this op-amp is connected as an amplifier with a closed-loop gain of 100, then the new upper cutoff frequency is
Question 111easy
An op-amp, having a slew rato of 62.8 V/msec, is connected in a voltage follower configuration. If the maximum amplitude of the input sinusoid is 10 V, then the minimum frequency at which the slew rate limited distortion would set in at the output is
