An NMOS amplifier is shown in Figure 1. Transistor M1 is biased in the saturation region for an amplifier application. The circuit is biased with a resistive voltage divider consisting of R1 and R2, a source degeneration resistor RS, and a load resistor RD. The drain bias current for the design is ID = 500 μA and VDS is 1.625 V. The device parameters are: L = 0.5 μm, W = 10 μm, kn’ = 200 μA/V2, Vtn = 0.5 V, and λn = 0. analyze the frequency response of the amplifier. a) Draw a midband small signal ac equivalent circuit model for the amplifier. For midband you can assume the reactance of Cin is sufficiently low that it is a short circuit. b) Derive an expression for the midband voltage gain transfer function Vout /Vsig. The amplified output signal is taken from the drain terminal and Vout = Vd. Write your gain function in terms of variables only. c) Evaluate the midband gain and calculate a value both in V/V and dB. d) Analyze the frequency response of the input network including the capacitor Cin. Find an expression for the transfer function H1(jω) = Vg/Vsig. e) Evaluate H1(jω) = Vg/Vsig and make a Bode plot of the magnitude of H1(jω).
