In this amplifier circuit, the high and low DC voltage sources are: VDD = 5 V and VSS = −5 V respectively. Consider that all three external capacitors have high values. The PMOS transistor has a threshold voltage equal to Vt = −1 V and kp = kp′(W/L) = 0.4 mA/V2, and the NMOS transistor has a threshold voltage Vt = 1 V and a kn = kn′(W/L) = 2 mA/V2. It was shown in HW#7 that the DC drain voltage of the PMOS transistor is −0.2 V and the DC source of the NMOS transistor is −2 V. a) Perform the small signal analysis of this circuit and determine the voltage gain: AV = Vo/Vi b) Determine the input and output resistance of this amplifier Rin and Rout . c) Discuss what is the purpose of the part of the circuit between CC2 and CC3 which includes the NMOS transistor in this amplifier design. d) Determine the parameters of a simple voltage amplifier model (discussed in chapter 1) which will represent this amplifier. Note that the parameters of the simple voltage amplifier excludes any series resistance of the external source ( Vi ) (in this case it is zero anyway) and the load resistance (in this case RL = 2 kΩ ). e) Using the simple model from part (c) determine the voltage gain AV = Vo/Vi and see if it agrees with the answer of part (a).

For the following problem, neglect body effect, Cgd and ro, but consider Cgs and use long-channel equations in transistors. Assume L = 0.7 μm for both transistors. The other circuit component values are the following: Rb = 4 kΩ, Rd = 50 Ω, Lg = 10 nH, Ls = 0.5 nH, RS = 50 Ω. The frequency of operation is 2.4 GHz. Ci may be considered as a short circuit at the frequency of operation. Rb is high enough that can be considered as an open circuit for small signal. (a) Symbolically, calculate the input impedance Zi. (b) Calculate the required overdrive voltage in M2 to make the real part of Zi equal to 50 Ω. (c) Calculate W2 to make Zi = 50 Ω. (d) Calculate ID and W1 to make Iref = ID/10. (e) Calculate the DC component at v0. (f) Numerically calculate the small-signal gain, av = vo/vi. (g) Calculate vo if vs = 1 mV peak. (h) Symbolically, calculate the noise figure of this amplifier. (i) Calculate F in dB. CMOS process data: VDD = 1.8 V. For NMOS, Vthn = 0.4V, μn = 400 cm2/Vs, Cox = 9 fF/μm2 and γn = 1. The parameters for PMOS transistors are k′ = μpCox = 90 μA/V2, Vthp = −0.4V and γp = 0.8.
