Abstract
A differential circuit with linearity correction loop includes a main differential amplifier , and a correction amplifier having inputs coupled to the outputs of the main differential amplifier through feedback paths. The output signals from the correction amplifier are combined with the inputs to the main amplifier such that a negative feedback loop is formed around the differential circuit. This feedback loop provides stability with only a minor power increase.
