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). The x-axis is ω (log scale) and the y-axis is the magnitude in dB. f) Use the LTSPICE circuit template and verify the frequency response of the amplifier circuit. Include a copy of the schematic and the frequency response plot. Use 20 points per decade and a frequency span of 0.1 Hz to 100 Hz.

To improve the performance of the differential amplifier shown in Figure Q1, the biasing current source is replaced by a Widlar current source. The collector resistors are replaced by a current mirror formed by the matched bipolar transistors Qs and Q6, and the bipolar transistors Q1 and Q2 are replaced by the matched field-effect transistors M1 and M2. A single-sided output at the drain terminal of M2 is used. The transistor parameters for the bipolar transistors are: β = 100, VBE (on) = VEB(on) = 0.7 V, and VA = 100 V. The transistor parameters for M1 and M2 are: Kn = 0.15 mA/V2, VT N = 0.8 V, λ = 0.01 V-1 . The improved differential amplifier is shown in Figure Q2. (a) Determine the quiescent voltages and currents of M1 and M2 when v1 = v2 = 0. (4 marks) (b) Design the value of resistor RE such that IQ = 0.1 mA. (2 marks) (c) Determine the maximum and minimum common-mode voltages that can be applied to v1 and v2. (3 marks) (d) Determine the percentage change in IQ when the common-mode voltage applied to v1 and v2 changes from the maximum to the minimum value obtained in part (c). (5 marks) (c) Define vd = v1 - v2, determine the differential-mode voltage gain Ad of the improved differential amplifier.
