Abstract
An operational amplifier has a bias circuit, a differential amplifier, an output stage, and a feed forward circuit. The bias circuit provides a reference. The differential amplifier is coupled to a pair of input terminals and provides a differential output based on the first and second inputs. The output stage responds to the reference and to the differential output so as to supply a current to an output terminal. The feed forward circuit responds to the differential output in order to increase and decrease current to the output terminal. As a result, the feed forward circuit extends the dynamic range of the operational amplifier.
