Response to the following problem:
The circuit in Fig. is fabricated in a 0.18-μm CMOS technology for which μnCox = 400 μA/V2, μpCox = 100 μA/V2, Vtn = -Vtp = 0.5 V, V_ An = 5 V/μm, /V / Ap / = 5 V/μm, and VDD = 1.8 V. It is required to design the circuit to obtain a voltage gain Av = -40 V/V. Use devices of equal length L operating at I = 100 μA and / VOV/ = 0.25 V. Determine the required values of VG, L, (W/L)1, and (W/L)2.
