Please restate your requirements, as I don't get it. Also, why are R4 & R5 0Ω ?
When component values are unknown the accepted practice is to state them as Rx, Cx, Lx, Zx, or, if you prefer, R?, C?, L?, Z?, etc. As for what part (exactly) that you lost me? ... Well, all of it because you can't re-write Ohms Law. Not even Congress or the Supreme Court can do that. Maybe Al Gore can but not quite sure about that.Sorry to hear you didn't get my requirements. In what part exactly did I lose you?
For the resistors: I just couldn't figure them out so I just left them 0. The purpose of the diagram was just to show the configuration I was looking at, not the actual values of resistors.
The Vcc is not a source of excitation. It's your power source. This includes oscillators, which have no external source of excitation.The Vcc is not the only source of excitation in the circuit. The current source is varied until I get a 5 mA peak-to-peak swing through the load and Vcc provides that extra current which causes the amplification. If Vcc was the only source in the circuit, then it would be just a DC biasing problem.
