1. Suppose the MOSFET drawn has Vth = 1 V, and Ip = 1 mA when Vov = 0.5 V. Vin Vin VDD = 5V Rp = 5 kn Vout Vs.VD. VDD (a) Calculate the Vin values that lead to off, linear, and saturation modes respectively. Indicate the boundaries of these regions on the Vin plot. (b) Draw a suitable 100 mV amplitude sinusoid for Vin that keeps the MOSFET working in saturation mode. (c) Draw three time-domain waveforms for VS, VD, VDD that correspond to Vin from part (b).

answer part b,c, and d
