Please answer in typing format please ASAP for the Please I will like it please I appreciate your support and I

Problem • Determine the input and output impedances of the given amplifier. The op-amp datasheet gives: Zin = 2 Mohm, Zout = 75 ohm, A = 200000. 4 Find the Closed-loop voltage gain. www R OV 220 ΚΩ R₁ 10 ΚΩ out

A type II compensator implementation for the above Buck converter is shown below. Ce2 Vout Cet HH Ret Vctrl R2 E/A Vset What should be the voltage Vref in the above type II compensator to produce 5V DC output if R# = 4k and R2=1k. а. Vet b. Write the small signal gain equation (-ctrl) between Vetrl and Vout- out с. Does R2 present in the above gain equation. Please add some explanation. d. How many poles and how many zeros are produced by this type II compensator?
