AN NMOS differential amplifier employing equal drain resistors, RD= 47 kΩ, has a differntial gain Ad of 20 V/V.(a) What is the value of gm for each of the two transistors?(b) If each of the two 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 lowest value that VDD must have to ensure saturation mode operation for Q1 and Q2 at all times? Assume V1= 0.5 V.
