    Hello all,

    I have a HW problem ( see attached PDF).

    What I am confused about is the 2mA current source. What I am thinking is that the emitter current = the collector current = 2mA for Q1 ( the first transistor in the pair ). If this is the case, does that mean that the base current of Q2 is 2mA?

    Also, since there is no voltage drop anywhere ( by way of resistors ) in the first transistor, how could there be a VCE1?

    Any help would be greatly appreciated

    Go ahead and post your attempts to computer the some of the values that the problem requires to be computed.

    The members can then comment and offer hints on where you may be having problems with your approach.
