For the current-mirror circuit shown on the left hand side, please answer the following questions. All the respective sizes of the transistors are given in the figure. Assume that Vtn = 1 V, kn = 5 mA/V2 for a unit size of NMOS which is (W/L).
a) Find the value of Vg and lout.
b) What is the required bias voltage Vb in order to maximize the output voltage swing? What is the minimum output voltage?
c) Find the value of Rout. (Assume that VA = 50 V for NMOS)
