The MOSFET in the amplifier circuit below in Figure 2 has threshold voltage V = 2V, MOSFET parameter ka =
HaCox(W/L) = 4mA/V?. Ignore channel length modulation. R1 = 1kQ, R2 = 1M2, R3 = 1MQ. VDD = 8V. As
labeled, input and output of the amplifier are nodal voltages of vin and vo, respectively.
The input voltage source has zero resistance and produces a signal vaig which is a sinusoidal signal with zero
average. Vsig= 10sin(t) in mV.t is time.
