Abstract
Current sources, systems including the current source, and methods for regulating and/or controlling a circuit using the current source. The current source is generally configured to (i) receive a reference current, a bias voltage and a feedback/input current and (ii) provide an output current. The systems generally include the current source, a circuit directly or indirectly receiving the output current, a bias source/generator configured to provide the bias voltage, and a current reference configured to sink or source a predetermined amount of current from or to the output current. The method generally includes (a) applying a bias voltage to the current source, the current source receiving an input current and providing an output current; (b) sinking or sourcing a reference current from or to the output current; (c) applying the output of the current source directly or indirectly to a regulated circuit; and (d) providing the input current from the regulated circuit.
