An NMOS differential amplifier employing equal drain resistors, RD = 47 Kohms, has a differential gain Ad of 20 V/V.
a) What is the value of gm for each of the 2 transistors?
b) If each of the 2 transistors is operating at an overdrive voltage VOV = 0.2 V, what must the value of I be?
c) For vid = 0, what is the dc voltage across each RD?
d) If vid is 20-mV peak-to-peak sine wave applied in a balanced manner but superimposed on VCM = 0.5 V, what is the value that VDD must have to ensure saturation-mode operation for Q1 and Q2 at all times? Assume Vt = 0.5 V.
