Using any number of Op-Amps, design multistage amplifier to amplify input Ac signal with 0.01V amplitude, the expected output voltage would have 4V amplitude.
The input signal frequency = 10 KHz.
Assume gain bandwidth product of Op-Amp = 1 MHz
The open loop gain of an op-amp is 92 dB. Given that the open loop corner frequency is 100 Hz, what is the
unity gain bandwidth of the op-amp?
