In the circuit below, the supply voltage is VDD = 2.5 V and the MOS transistors have process transconductance parameters μnCox = 0.3 mAV2 and μPCox = 0.2 mAV2, threshold voltages Vtn = −Vtp = 0.4 V, channel-length modulation coefficients λn = −λp = 0.1 V^−1, and channel lengths L1 = L2 = 0.2 μm. (a) Choose the widths of the transistors, W 1 and W 2, and the gate bias voltages, VG1 and VG2, such that the dc output voltage be Vo = VDD/2 and all transistors operate in saturation with an overdrive voltage of 0.5 V and a drain current of 85 μA. (b) Find the small-signal voltage gain vo/vi. Calculate the largest peak-to-peak amplitude of the input sinusoid vi and the corresponding amplitude of the output sinusoid vo that the circuit can handle while all transistors remain in saturation region.

The following parameters are for both M1 and M2 transistors: Vdd = 2.5v Vbs = 0 Vt0 = 0.5v lambda = 0.11v-1 W/L = 10 unCox = 200.0 uA/V2 a) For VIN equal to 1.25 V, what region is transistor M1 operating in? Find VOUT . b) For VIN equal to 2.0 V, what region is transistor M1 operating in? Find VOUT. c) Create a small signal model for this circuit. Find open circuit gain AV. d) For VIN equal to 1.25 V, Find the value for open circuit voltage gain, AV. Hint: Need values for gM1, gM2, rOM1, rOM2; combine two small signal models, one for each transistor, to find the final small signal model.

Calculate DC biasing (20 points), of the following circuits. |Vth| = 0.5 V, λ = 0, μCoxWL = 0.2 A/V2 for all devices. DC biasing means the biasing currents and the output voltages. If we keep the currents as calculated and try to minimize the vdd, what would be the the lowest vdd for the circuits. Assume PMOS's parameters are exactly the same as the NMOS (20 points).
