ABSTRACT:
An apparatus comprising a Darlington transistor pair and a bias circuit. The Darlington transistor pair may be configured to generate an output signal at an output node in response to an input signal received through an input node. The bias circuit may be coupled between an output transistor of said Darlington transistor pair and the input node. The bias circuit generally comprises (a) a bias transistor, (b) a bypass capacitor, and (c) a resistor connected between a base of the bias transistor and base of the output transistor.
