description A current source providing a voltage-controlled variable-current reference is described which employs a conventional current mirror to supply a current to a diode-connected transistor, and to a plurality of controllable current paths, wherein the controllable current paths are controlled by voltages from a voltage sensing circuit so that predetermined amounts of current are drawn away from the diode-connected transistor as function of a controlled voltage, so that the diode-connected transistor generates a voltage as a function of the current flowing through it which voltage is used to control an output transistor and a current flowing through the output transistor.
