ABSTRACT:
A common-mode signal sensor for supplying a common-mode signal in response to a difference signal. A first input terminal and a second input terminal receive the difference signal and an output terminal supplies the common-mode signal. A first differential pair of a first conductivity type is connected to a first current source at a first node and has its control electrodes connected to the input terminals. A second differential pair of a second conductivity type opposite to the first conductivity type is connected to a second current source at a second node and has its control electrodes also connected to the input terminals. A diode-connected fifth transistor of the first conductivity type is connected between the first node and the output terminal and a diode-connected sixth transistor of the second conductivity type is connected between the second node and the output terminal.
