I want to use a voltage of 0-5 volts to output two matched currents between 0 and 1 mA (to control a pair of OTAs)
This circuit works in Falstad, but will differences between the transistors mean that it doesn't work IRL? I understand that I could match transistors based on VBE, but is there any kind of feedback mechanism here that would cause all the current to come out of one transistor only, for example?
I think the "current mirror" concept is related to this but I am a complete noob
