Solve the following:
Q: For the NMOS amplifier in Fig.replace the transistor with its T equivalent circuit, assuming λ = 0. Derive expressions for the voltage gains vs/vi and vd /vi . In the circuit of Fig. the NMOS transistor has = 0.5 V and VA = 50 V and operates with VD = 1 V. What is the voltage gain vo/vi ? What do VD and the gain become for I increased to 1 mA?
