An enhancement mode MOSFET class AB output stage, The threshold voltage of each transistor is Vtn=-Vtp=1V, and the conduction parameters of the output transistors are Kn1=Kp2=5mA/V^2, Let Ibias=200uA.
Determine Kn3=Kp4 such that the quiescent drain currents in M1 and M2 are 5mA.
and using the results of part find the small signal voltage gain Av= dv0/dv1 evaluate at: (i)vo=0 and (ii) vo= 5V.
