Find the expressions for the total instantaneous quantities v C (t), v B (t), i C (t), and i B (t). 2 Fig.2 3The transistor amplifier shown in Fig. 3 is biased with a constant current source I and has a very high . a) Find the dc voltage at the collector V c . b) Find the value of g m . c) Replace the transistor with the hybrid model and find the voltage gain A v =v c /v i . (note that the dc current source I should be replaced with an open circuit for ac analysis) Fig.3 Due date: October 28, 2008. Late submission will not be accepted. C B...
