MASSACHUSETTS INSTITUTE OF TECHNOLOGY Department of Electrical Engineering and Computer Scienc e 6.012 Microelectronic Devices and Circuits Homework 7 Problem 1 You are given a CS amplifier and NMOS device parameters shown below. The current source supply provides 100μA and has an infinite output resistance, (i.e. ISUP = 100 μA and roc ). The current source supply must have at least 0.5 V across it in order to maintain the high output resistance. W / L = 150/1.5 V = 0.5 V Tn a) Calculate V BIAS such that V OUT = 0 V. b) Draw the two-port model and calculate the two-port parameters R in , R out , and A v . c) Calculate the overall voltage gain
