Patent abstract
A DC offset elimination device includes a first signal path that delivers a differential input signal pair from an input node to an output node and a second signal path that delivers a differential output signal pair from the output node to the input node. The second signal path includes a first transconductor having an input terminal coupled to the output node, an amplifier having an input terminal coupled to an output terminal of the first transconductor, a capacitor coupled in parallel to the amplifier, and a second transconductor coupled to the output terminal of the amplifier and to the input node.
