In the following circuit, assume that λ = γ = 0, VDD = 3 V, |VTH| = 0.5 V, μPCox = 20 μA/V2. Furthermore, assume that vin is a small signal source and Vbias1 = 1.5 V and the DC level of Vout1 and Vout2 are all equal to 0.5 V and 1.5 V, respectively. Also, assume that the bias current of M1 is twice that of M2. (Hint: ID = 1/2μpCOX(W/L) (|VGS| − |VTH|)^2, in saturation) (1) What is the region of operation of M1 and M2? (10 points) (2) If the overall power consumption is 3 mW, find R1, R2, (W/L)1, (W/L)2. (15 points) (3) What is the small signal gain of the circuit (vout2/vin)? Assume there is no parasitic effect and gm1 = gm2 = 4/3 mV/V. (15points)

Transistors operate in the saturation region. Please use subscripts to refer to M1 and M2. VB is a bias voltage. Please ignore backgate effect. Please consider ro. Do NOT include any capacitors. Do NOT need to show results in a fully expanded form. (1) Draw the small-signal model of the differential-mode half circuit. Provide a symbolic expression for the differential-mode voltage gain. (2) Draw the small-signal model of the common-mode half circuit. Provide a symbolic expression for the common-mode voltage gain.
