Hello people! I've seen this diagram many times over and I'm having trouble getting my brain around what is constant in it: [image] My reasoning: if we change Vcc, we get different Ic. If we change the resistors, we get different values across the entire circuit. Ic(max) = Ib * β Changing the …

What is constant in a BJT contant current source?

This is a circuit that keeps a constant current "even if the load resistance was fluctuates" when using a fixed VCC.
VCC must be a fixed for standard uses.
