The first stage of a two stage amplifier has an input resistance of 20 KO, an output resistance of 6 KO, and an open circuit voltage gain of 15. Design a second stage (Rin, Rout, and Av) to meet these specifications:a) the two-stage amplifier has an open circuit voltage gain of 120b) the open circuit voltage gain of the second stage must be in the range 50-100c) the input resistance of the second stage should be a minimumd) the two-stage amplifier has an overall gain of 60 for source resistance of 8 KO and the load is a 4 KO resistor.
