Response to the following :
(a) The transistor parameters are β = 125 and VA = 200 V. A value of gm = 95 mA/V is desired. Determine the required collector current and then find rπ and ro.
(b) A second transistor has small-signal parameters of gm = 120 mA/V and rπ = 1.2 kΩ. What is the quiescent collector current and the transistor current gain?
