A one-pole amplifier offers a voltage gain of 10,000 (A=10,000) and a 3-dB cut-off frequency of 100 Hz. An analog design engineer uses this amplifier to build an amplifier with negative feedback. The closed-loop gain of the amplifier with negative feedback is 50. a) The loop gain (kAo) b) The 3-dB bandwidth of the amplifier with negative feedback is kHz.
