A transconductance amplifier with input Vs and output Io is shown in Fig. 2. The transistor is specified in terms of gm and ro. Neglect the body effect. (a) (4 points) Sketch the small-signal equivalent circuit using the hybrid-π model of the MOSFET. (b) (8 points) Show the output resistance is given by Rout = ro + RS + gmroRS. (c) (8 points) Derive the expression for Gm ≡ Io/Vs Vout = 0 in terms of gm, ro, and RS.

(a) Choose VB such that M1 is 300mV away from the triode region (VDS1 = VGS1-VTH1+300mV; M1 and M2 operate in Saturation region). (b) Calculate the small-signal voltage gain (VOUT/VIN). (c) Assume VB = 1.43 V, calculate the maximum output voltage swing to keep all transistors in saturation. Neglect channel length modulation. (d) Assume the maximum output swing is VOUT = 2.23 VPP, Calculate the swing at node X. In Fig. 2, assume (W/L)1 = 12 μm/0.18 μm, (W/L)2 = 24 μm/0.36 μm, ID1 = ID2 = 0.5 mA, and RD = 2 kΩ, VTH,N = 0.5 V, μnCox = 150 μA/V2, VDD = 3.3 V, λn = 0.1 V-1. Neglect body effect. Neglect channel length modulation except doing output impedance calculation.
