ABSTRACT:
A differential amplifier includes a differential amplifier section to generate a current composed of a differential-mode current and a first common-mode current according to a differential-mode component and a common-mode component of an input signal, a common-mode current generator section to generate a common-mode current according to the common-mode component of the input signal, and a current amplifier section to receive the current and the common-mode current, amplify a difference between the current and the common-mode current and output a result.
