Consider the amplifier circuit shown in the figure below. MOSFET channel length modulation can be neglected, VDD = 5 V, Vtn = 0.7 V, and kn = 1 mA/V2. Find VOV, ID, RD and RG to obtain voltage gain equal to −25 V/V and an input resistance of 0.5 MΩ. What is the maximum allowable input signal, vi? Tip: during small signal analysis you can assume that current through resistor RG is much smaller than gmvGS current and check if this is satisfied later. (Ans. 0.319 V; 50.7μA; 78.5kΩ; 13MΩ; 27mV)

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.

It is required to bias the MOSFET amplifier shown in Fig. 1 below at point Q for which VOV,Q = 0.2 V and VDS,Q = 1 V. It is required to bias the MOS amplifier of Fig. 7.3 at point Q for which VOV = 0.2 V and VDS = 1 V. Find the required value of RD when VDD = 5 V, Vt = 0.5 V, and kn = 10 mA/V2. Also specify the coordinates of the VTC end point B. What is the small signal voltage gain of this amplifier? Assuming linear operation, what is the maximum allowable negative signal swing at the output? What is the corresponding positive peak input signal?

A differential amplifier circuit is shown in the figure below. In the circuit, VDD = +10 V, the current I provided by the current source is 2 mA and the internal source resistance is RSS = 50 kΩ. The transistor parameters are as follows: - All NMOS: μnCox = 100 μA/ V2, W/L = 10 μm/1.6 μm, Vtn = 0.7V, λnL = 0.10 μm/V - All PMOS: μpCox = 50 μA/V2, W/L = 10μm/1.6μm, Vtp = −0.8 V, λpL = 0.05 μm/V (1) Calculate the DC output voltage VO (ignore the channel length modulation effect of all transistors). (2) Under the differential mode operation (i.e., v1 = 1/2vd, v2 = -1/2vd ), calculate the differential mode small signal voltage gain Ad = vo/vd (include the channel length modulation effect of all transistors). Hint: please pay special attention to the connections of Q3 and Q4 transistors.
