EEE 3308C Spring 2011 Quiz No. 1A Solution Consider the following circuit. The transconductance amplifier specs are 30kohm input resistance, 50 mA/V short-circuit transconductance, and 8kohm output resistance. a) Write down the equivalent circuit for the transconductance amplifier. b) Compute the overall voltage gain, vo/vs, in dB. c) If R i and R o of the transconductance amplifier could be modified to their optimal values (all other parameters the same), what would be the maximum possible overall voltage gain in V/V? kohm
