I'm trying to design a current source with some particularities. Based on the modified Wilson current source, I need an output stage that provides no voltage when there is no load, that's the problem, because when there is no load on the circuit, the output voltage is maximum (close to V1 voltage).
So, I need to do something that pulls the Q4 collector voltage to ground when no load and provides the current controlled by V2 and Q5 when some load is attached. Can someone help me with this?
