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.

The amplifier circuit below uses an n channel FET with gm = 4.74 mS and ID0 = 4.53 mA. The resistor R1 = 2.38 kΩ and VDD = 20.7 V. a. Analyse the circuit to find an equation for the output voltage in terms of the input voltage. You do not need to submit this equation for this quiz, but you will need it to solve the following problems. (Hint: begin by using KVL to find an equation for vout in terms of iD and values we already know. Then write an equation for the FET that gives iD in terms of vGS. Combine these two equations to eliminate iD. ) ) In the following parts, give your answer to 3 siginficant figures as usual (except for part c), but keep intermediate results to more significant figures, otherwise rounding errors may lead to incorrect answers. b. What is the small signal gain of the amplifier (dvout dvin ) ? −11.3 c. What is the minimum output voltage of the circuit? (For this part only, give your answer to the nearest whole number. ) 0 V d. What is the (minimum) value of vin that corrsponds to the output voltage from part c)? Number V e. What is the maximum output voltage of the circuit? 20.7 V f. What is the (maximum) value of vin that corrsponds to the output voltage from part e)? Number Units
