ABSTRACT:
The current mirror circuit comprises a feedback transistor whose emitter and collector are connected between the collector and base of the input transistor. The base of the feedback transistor is grounded. Due to the presence of the feedback transistor, the potential at the collector of the input transistor can be set at a potential which is lowered from the Vcc potential by a saturation voltage between the emitter and collector of the input transistor.
