Given two NMOS FETs having (kn'/2)(W/L) = (3 KW)^-1 and Vt = 3V. Using a single 10V dc power supply, design a differential pair amplifier having 1mA bias current in each transistor. What is its maximum gain for linear operation (balanced input, balanced output)? Assume ro = 8.
Hint: Increase the value of RD until the MOSFETs leave their saturation regions.
