Response to the following question:
An NMOS differential pair is to be used in an amplifier whose drain resistors are 10 kΩ ± 1%. For the pair, Kω nW/L =4 mA/V2. A decision is to be made concerning the bias current I to be used, whether 160 μA or 360 μA. Contrast the differential gain and input offset voltage for the two possibilities.
