Question

For the questions below, assume the following device parameters:

K'n=μnCox=200 μA/V², K'p=μpCox-80 μA/V², |VLIN] = infinite

Vto,N=| Vto,P|= 0.5V, PHI= |20F|=0.85V for N and P, y=0.3 V0.5, λ=0.1 V-¹/n4) Design a single-stage differential amplifier with a current-mirror load (see Lec 8) and a current-

mirror tail current that can provide a diff-mode gain >32 dB with CMRR > 60 dB. You may

cascode any part of the circuit. Total current consumption should be less than 1 mA.

a. Please draw a clear schematic of the circuit with all W and L dimensions for each device

clearly marked.

b.

Validate your design by calculating the achieved Adm in dB

c. Validate your design by calculating the achieved Acm and CMRR (both in dB)

d. Finally, estimate the common-mode input range for your circuit.
