A dynamic feed-forward OPAMP-based circuit is provided. A first amplifying stage amplifies a pair of input differential signals to provide a pair of intermediate differential signals. A second amplifying stage amplifies the pair of intermediate differential signals to provide a pair of output differential signals. A first capacitor is coupled to a non-inverting input terminal of the first amplifying stage. A second capacitor is coupled to an inverting input terminal of the first amplifying stage. A feed-forward transconductance stage is coupled between the first and second capacitors and the second amplifying stage. The first and second capacitors and the feed-forward stage form a high-frequency path with a first gain curve, and the first amplifying stage and the second amplifying stage form a high-gain path with a second gain curve. The operational amplifier provides an open-loop gain according to the first and second gain curves.
