They Do It with Mirrors
We examine a simple two transistor current mirror, a circuit that regulates its output to have an equal current to its input. The circuit can be used to balance the currents in two parts of a larger design, or to reverse the direction of current flow (turn a current source into a current sink, or vice versa).
Schematics are on the project GitHub: https://github.com/kennykb/kevins-cav...
