ABSTRACT:
A reference voltage generator is presented for use in a differential amplifier. The reference voltage provided by the generator tracks the non-signal dc conditions of a differential input stage and provides a reference voltage to a level-shifting stage so that feedforward compensation can be used to provide extended bandwidth without settling time problems.
