CURRENT MIRRORS

M3 out lim

µn= 0.05 m2V-1s-1, µp= 0.02m2V-1s-1, Cox= 0.0125 F/m2, Vthn=0.4V, Vthp= -0.4V, λn=0.1 V-1, λp=0.3 V-1

VDD=1.8V

W1= 40µm; W2=W3=80µm; all L are 0.5µm. RL=4k; VIN=0.5V

  1. Calculate voltage gain of the circuit below ignoring channel length modulation.
  2. Calculate voltage gain of the circuit below including channel length modulation in small signal circuit.
