ABSTRACT:
A current mirror circuit that can be disabled has been provided. An enable signal is applied to the base of a transistor that drives the common bases of an emitter-coupled pair of transistors. A voltage level of the enable signal may be used to turn off the transistor which subsequently turns off and disables the emitter-coupled pair of transistors.
