Please be detailed, need to learn how to do this for futureexams. thank you
Fig. 2 shows a MOS differential amplifier. Let Q1 and Q₂ be matched, and Q3 and Q4 be matched. a) Find the differential half-circuit and use it to derive an expression for Ad in terms of gm1,2, gm3,4, ro1,2 and ro3,4 b) Neglecting the effect of the output resistances ro, find Ad in terms of µn, µp, (W/L)1,2 and (W/L)3,4. c) If µn=4μp and all four transistors have the same channel length, find (W1,2/W3,4) that results in Ad =10V/V.
