c) A feedback amplifier has a low frequency loop gain (Ao * ß) of 2000 and tow poles at fp1 = 300kHz, fp2 = and 2MHz. A dominant pole (fpD) is to be added such that the phase margin equal to 55°. Assuming the original poles (fp1 and fp2) remain fixed, determine the dominated pole frequency (fPD). This amplifier needs to be stabilized by moving the first pole (fp). Assuming fp2 remains constant, determine the dominated pole frequency (fPD) that replace fpi. State your conclusion from the results obtained (talk about the stability, f, fpd, phase margin).

A voltage-voltage feedback amplifier employs a basic amplifier with input resistance of 20 MOhms, output resistance of 2kOhms and gain A = 1000. The feedback factor k = 0.1. The closed loop input resistance Rince, and the closed loop output resistance Rociof the closed-loop amplifier are: Rincl= Gand Rout 2
