Abstract
Differential amplifiers are provided that substantially cancel the input bias currents at the inputs to the differential amplifiers. A circuit produces a compensation current that is substantially equal in magnitude but opposite in polarity to input bias currents associated with the first and second inputs of the differential amplifier. A further pair of transistors are used to replicate the compensation current, and to provide replicated compensation currents to the inputs of the differential amplifier, thereby substantially canceling the input bias currents at the inputs.
