The model of an Amplifier is shown below connected to a small signal source Vsig having a series resistance Rsig and to a load resistor RL via coupling capacitors CC1 and CC2 as shown. a) Considering that the magnitude of a capacitor's impedance for sinusoidal sources is ZC = 1/ωC, derive an expression for the magnitude of the voltage gain (Av = Vo/Vsig) as a function of frequency. b) Simplify the expression of part (a) when the source frequency is high and thus the impedances of the capacitors can be considered to be very small. c) Discuss what happens to the gain when the source frequency is low and thus the impedances of the capacitors can be considered to be very high.

The model of a voltage Amplifier is shown below connected to a small signal source vs having a series resistance Rs and to a load resistor RL. a) If the amplifier's input resistance (Ri) is 100 kΩ, what is the range of values that the series resistance Rs can have if we wish 90% or more of the small signal source signal to be coupled into the amplifier. b) If the amplifier's output resistance (Ro) is 2 kΩ What is the range of values that the load resistance RL can have if we wish 90% or more of the amplifier's dependent voltage source voltage to be delivered (i. e. dropped) to the load resistor.

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.
