Abstract
A current mirror amplifier comprising a master mirroring transistor with collector-to-base connection for adjusting its emitter-to-base potential to condition it to conduct input current applied to its collector-emitter path, a plurality of slave mirroring transistors arranged to respond to an emitter-to-base potential equal to that of the master mirroring transistor for conducting an output current through its emitter-collector path proportional to the input current, a further transistor with its collector-emitter path arranged to sense the collector current of one of the slave mirroring transistors, and a component current mirror amplifier responding to the base current of the further transistor flowing through its input connection to supply a substantial share of the base current needs of said mirroring transistors at its output connection.
