For all circuits, do not consider channel length modulation for calculating bias points. Unless otherwise specified, channel length modulation effect needs to be considered for small-signal analysis. All answers should be given to the second decimal place. Circuit and device parameters are: Vdd = 5 V; VTnn = VTp = 1 V; μnCox = 50 μA/V2; μpCox = 25 μA/V2; λn = λp = 0.01 V−1; Lmin = 1 μm Figure 1 (for problems 1-3) Figure 2 (for problems 5-9) Figure 1: Transistor M1 has (W/L) = (160 μm/2 μm) and a bias current Iout = 2 mA. We desire M1 to be in saturation. You should assume λn = 0 for problems (1)-(3). Determine the ratio R1 /R2 required. 1 point Let VTn increase by 10% to 1.1 V.
