Abstract

A differential-pair amplifier comprising a transistor pair. The differential-pair amplifier includes a current source coupled to the transistor pair for providing a bias current to the transistor pair. The differential-pair amplifier also includes a switching mechanism coupled to the transistor pair for steering the bias current away from the transistor pair when disabling the amplifier operation. A system and method in accordance with the present invention allows fast enabling and disabling of a differential-pair amplifier. This fast switching technique can be used in the signal paths where the switching time is critical.
