WebConceptually, an ideal current mirror is simply an ideal current amplifier with a gain of -1. In Chapter 8 we explored the transistor and you should recall that the BJT device is a current amplifier of sorts (current controlled current source) in that the collector current is β times the base current. WebThe BJT (Bipolar Junction Transistor) is a semiconductor device that has mostly replaced vacuum tubes. The device is a current-controlled device, meaning that the collector or emitter output is a function of the base current. A BJT transistor’s mode of operation is essentially dictated by the current at the base.
