Multistage Amplifier In this last question, you are going to design a 2-stage amplifier. The first stage is a common-source amplifier and the second is a source follower, as shown in the figure below: Some parameters you may use are: VDD = 5 V, μnCox = 0.2 mA/V2, μpCox = 0.1 mA/V2, λn = 0.06, λp = 0.03, γ = 0, VTHN = 0.7 V, VTHP = −0.6 V; allow RL = 2 KΩ. Note: CS is large enough so that it will act as a short circuit for frequencies of interest. The circuit should satisfy the following specs: Total power consumption = 6.5 mW (use this spec to find total current drawn from VDD) The ratio of power consumed by the biasing branch: the amplifier: the follower stage should be 1:2:10 CS stage should provide a gain equal to −40 V/V Source follower stage should have a gain of 0.6 V/V Vomax = 3.8 V Find the W/L of all transistors and value of RD. Make reasonable simplifications.

Cascode Stage. Design a Cascode amplifier shown in figure below to achieve a gain of 1600. Assume VDD = 1 V, Vth = 0.3 V, λn = 0.2 V−1, γ = 0, μnCox = 100 μA/V2, I1 = 1 mA, gmro ≫ 1. a) Find bias point (VGS−Vth of transistors) to achieve the target gain such that we achieve maximum swing at Vout. b) Find W/L for each transistor. c) Calculate optimal Vb and VIN DC bias to maximize output swing. What is this maximum/minimum voltage levels at the output? What is the maximum swing? d) Notice you must generate a specific Vb externally to maximize the swing. If a lazy designer decides to connect Vb to VDD instead, what would be the swing in this case? e) To realize the current source load, we will use a PMOS active load. For PMOS, use the same parameters with λp = 0.2 V−1, μpCox = 50 μA/V2. Assume the bias current will remain at 1mA, find the new gain value. What would be the W/L for PMOS if we want to have a VOD(VGS−Vth) of 0.1V for this device. f) Repeat part (e) for a PMOS load with 2L gate length. g) It seems like making the PMOS load very large (large W) is beneficial to reduce VOD and consequently improving the voltage swing. What do you think is the drawback?

Assuming that transistors M1 is properly biased ( Vin has a proper DC component and a small-signal component) and M1 and M2 are operating in the saturation region, and capacitor C is large enough such that at the frequency of the input small signal it can be considered as a short circuit, find Find RL such that the magnitude of the small-signal gain of the circuit, namely, ∣Vout/Vin ∣ is 5 V/V. In the following circuit we have: VDD = 3 V (W/L)3 = (W/L)5 = (W/L)6 = 10 (W/L)4 = 40 (W/L)2 = 100 (W/L)1 = 25 R = 1 kΩ The technology parameters are: λ(NMOS) = λ(PMOS) = 0 V−1, γ = 0, VTH(NMOS) = ∣VTH(PMOS)∣ = 0.5 V, μnCox = 0.5 mA/V2, μpCox = 0.25 mA/V2.

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.
