Abstract:
A bipolar differential output circuit includes an input differential bipolar stage for receiving an input signal and generating a differential output current. An output differential pair of bipolar transistors without a bipolar tail current source responds to the input signal by providing a representative output signal. And a current mirror circuit passes current from the input differential pair to the output differential pair.
