The MOSFET in the amplifier circuit of Fig. P7.124 has Vt = 0.6 V and kn = 5 mA/V^2. We shall assume that VA is sufficiently large so that we can ignore the early effect. The input signal vsig, has a zero average. It is required to bias the transistor to operate at an overdrive voltage Vov = 0.2 V. What must the dc voltage at the drain be? Calculate the dc drain current ID. What value must R_D have? Calculate the value of gm at the bias point. Use the small-signal equivalent circuit of the amplifier to show that

It is required to bias the MOSFET amplifier shown in Fig. 1 below at point Q for which VOV,Q = 0.2 V and VDS,Q = 1 V. It is required to bias the MOS amplifier of Fig. 7.3 at point Q for which VOV = 0.2 V and VDS = 1 V. Find the required value of RD when VDD = 5 V, Vt = 0.5 V, and kn = 10 mA/V2. Also specify the coordinates of the VTC end point B. What is the small signal voltage gain of this amplifier? Assuming linear operation, what is the maximum allowable negative signal swing at the output? What is the corresponding positive peak input signal?
