Abstract
A switchable current amplifier comprising first and second transistors of complementary conductivity type, an input terminal connected to the emitter electrode of the first transistor, an output terminal to which the collector electrode of the second transistor connects, an inverting current amplifier having an input connection to which the emitter electrode of the second transistor connects and having an output connection to the base electrode of the first transistor. A control circuit is connected to an interconnection between the collector electrode of the first transistor and the base electrode of the second transistor for selectively diverting --in response to a control signal--collector current flow from said first transistor away from flowing as base current to the second transistor, thereby selectively disabling current amplification between the input and output terminals.
