For the CFIA, find vo/vi using the small-signal circuit. Assume ro1,2 = ∞, but consider the body effect of M2 (for M1, assume the body is tied to the source, so no body effect). Comment on how the body effect impacts the voltage gain.

For the circuit shown in Figure 2, VDD = 5 V, and transistors M1 and M2 have properties µnCox = 200µA/V2, (W/L) = 10, Vt0 = 0.7 V, and λ = 0. You may neglect the body effect below, unless you are specifically asked to consider it. Figure 2. Circuit for Problem 2. a) Draw the circuit above, and label the drain, gate, source, and bulk nodes for both transistors, using labels VD1, VG1, VS1, and VB1 for the drain, gate, source, and bulk nodes of device M1, respectively, and similarly for M2. In total, there should be 8 labels in your schematic. For this part, assume the transistors are in saturation. b) Determine the valid input range for the circuit under consideration; that is, determine the range on the input voltage Vin such that transistors M1 and M2 are operating in the saturation region. Note that, in your analysis, you are not constrained to Vin values between 0 V and VDD, inclusive; e.g., if Vin = 100 V keeps both of the transistors in saturation, then Vin = 100 V should be included in your range of valid input voltages. Your answer to this part should take the form Vin,low ≤ Vin ≤ Vin,high ; hopefully, it is obvious that you are being asked to provide numerical answers for the lower- and upper-bounds Vin,low and Vin,high , respectively. c) For the valid input range that you determined in part (b), determine the corresponding output voltage range; that is, determine Vout,low ≤ Vout ≤ Vout,high when the input is constrained to Vin,low ≤ Vin ≤ Vin,high. . As before, you should report numerical values for the lower- and upper-bounds Vout,low and Vout,high, , respectively. d) Determine the "on voltage" VON2 (or, as in the Sedra/Smith textbook, the "overdrive voltage") and drain current ID2 of transistor M2 over the range of valid input voltages. Also, determine the drain current ID1 of M1 over the valid input range. e) If you were to consider it, would any of the transistors in the circuit above be affected by the body effect? If "yes," then list the device (or, devices, as the case may be). Qualitatively speaking, how would your answers to parts (b) and (c) change if you were to take the body effect into account? Explain your reasoning.

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.
