Abstract
A differential circuit includes main transistors differentially coupled for converting differential input signals into main differential currents at output terminals. The differential circuit also includes compensation transistors coupled to the main transistors for converting the differential input signals into compensation differential currents at the output terminals. Each compensation differential current has an exponential current-voltage characteristic for improving linearity of the differential circuit.
