Abstract:
In one embodiment, an integrated circuit current mirror circuit is disclosed. The integrated circuit current mirror circuit includes a reference circuit, an output circuit and a mode selector circuit. The reference circuit includes an input terminal that receives a reference current. The output circuit generates an output current that is proportional to the reference current. The output circuit is coupled to a load circuit. The output current is provided to the load circuit. The mode selector circuit is coupled to the reference circuit and the output circuit. The mode selector circuit receives a plurality of mode control signals having different voltage levels. The mode selector circuit selects one of the mode control signals. The selected mode control signal is routed to the reference circuit and the output circuit to place the current mirror circuit in a desired mode.
