Apparatus and methods for electronic amplification

An amplifier comprising:

• a signal amplification block configured to receive a differential input voltage signal and to amplify the differential input voltage signal to generate an output signal;
• and
• a feed-forward offset correction block configured to receive the differential input voltage signal and to generate an input offset correction signal, wherein the feed-forward offset correction block comprises:
• a first feed-forward amplification circuit configured to amplify the differential input voltage signal to generate a feed-forward signal;
• a feed-forward chopping circuit configured to chop the feed-forward signal at a chopping frequency to generate a chopped feed-forward signal;
• and
• a notch filter configured to attenuate the chopped feed-forward signal at the chopping frequency to generate a notched signal, wherein the feed-forward offset correction block is configured to generate the input offset correction signal based at least partly on the notched signal, and
• wherein the signal amplification block is further configured to receive the input offset correction signal from the feed-forward offset correction block and to reduce an input offset voltage of the amplifier using the input offset correction signal.
