ABSTRACT:
An apparatus comprising a Darlington transistor pair, a first common-base transistor and a second common-base transistor. The Darlington transistor pair may be configured to generate an output signal in response to an input signal. The first common-base transistor may be coupled between the Darlington transistor pair and the output signal. The second common-base transistor may also be coupled between the Darlington transistor pair and the output signal. The first and second common-base transistors may each have a base configured to receive a reference voltage.
