For the differential amplifiers below, Vinl = +Vid 2 and Vin2 =-Vid 2. The cireuits are perfectly symmetrical and À >0 (i.e. do not ignore ro). Find the differential voltage gains of the circuits. Indicate + and - signs for the Vout so that the gain is positive. (Hint: You can use the differential half circuit method and -GmRout method which were demonstrated during problem solving session.)
