Hi,
I have the following current mirror circuit. Lets assumeI change the load resistance from a small value to a higher value. I dont see how this changes the current Ip. However the Vce of the transistor Q2 changes which may cause the current to change.
Now , by adding a resistor to the collector , it appears that it improves. I dont understand how this is changing and helping to change load varaition vs current stability.
