Consider the p-channel MOSFET (M1) shown in the left figure below. Which region is it operating in? If W/L = 20, μpCox = 100 μA/V2, VT = -0.4 V, calculate the drain current. Note that the source is the terminal with the arrow. In a PMOS FET, VDS and VGS are negative. The circuit symbol for a PMOS FET is shown below (right). Hint: You can assume that the FET is operating in saturation and then find VD. After finding VD, verify saturation condition is met. If it satisfies the saturation condition, then the assumption in justified.

In this question, you are asked to find the effective transconductance (Gm) and the resistance into the drain (Rx) of a common-source amplifier with source degeneration. Based on the results, the voltage gain of a common-source amplifier with source degeneration will be evaluated a) The figures shown below are a circuit to find the effective transconductance (G) of the NMOSEFT with source degeneration (left) and its corresponding small-signal circuit (right). It is noted that the output is shorted to VDD (ac grounded) since the definition of effective transconductance is the ratio between the short-circuit output current and the input signal voltage. Prove that Gm is given by Gm = id/vin = gm/1+gmRs In this calculation, the current passing through ro can be neglected since, in general, ro is very large when the NMOSFET operates in saturation region and so this current is very small. Thus, the indication of id is the current of the voltage-controlled current source (gmvgs) only. b) The figure shown below is the method to evaluate the resistance looking into the drain (i.e. Rx) of a source-degenerated NMOSFET. The circuit is shown on the left while the equivalent small-signal modeling is shown on the right. It is noted that the bias condition (VBiAS) is set so that the values of gm and ro, can be defined. Moreover, there is no input signal (i.e. Vin = 0) since we would like to see the value of Rx which is due to the circuit only but not due to the external effect. Based on the above small-signal model, prove that RX = ro(1 + gmRS) The complete common-source amplifier with source degeneration is shown below. c) The complete common-source amplifier with source degeneration is shown below. Prove that the voltage gain of this amplifier is given by v. Vin Explain the reason(s) why the voltage gain is negative. What is the physical meaning of negative voltage gain?

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.

Consider an NMOS whose G, S, D terminals are connected as shown in the figure below. Note that the voltage VGD is applied across the gate and drain and VGD = VG−VD. The threshold voltage of the MOSFET is Vth . First determine the MOSFET region of operation and then write the equation for IDS as a function of VDS and sketch the IDS−VDS curve, for: (a) VGD = 0 V; (b) VGD = Vth/2; (c) VGD = 2 Vth.
