Question

Enclosed figure has common gate amplified circuit designed with MOS transistor.

Following values are given for circuit:Vdd = 15V RL = 9KΩ Is = 2mA.Transistor Vth = 1V,  Kn = ½.µ.Cox.W/L = 2mA / v²,λ= 0 and Vt = 25 mV.

  1. Draw DC model of circuit.
  2. Calculate the RD value required to have VDSQ = 11V for the transistor.
  3. Please calculate gm ve ro values for transistor.
  4. Draw the small signal equivalent circuit of the circuit and calculate the AV = VO / Vin voltage gain.
