Apparatus for offset correction in electronic circuitry and associated methods
09742397 · 2017-08-22 · ·

An apparatus includes a first field effect transistor (FET) that has a body and is coupled in a circuit. The apparatus also includes a second FET that has a body and is coupled in the circuit. The circuit has an offset because of a mismatch. The apparatus further includes an offset correction circuit coupled to the body of the first FET and to the body of the second FET. The offset correction circuit provides a first offset correction signal to the body of the first FET and provides a second offset correction signal to the body of the second FET.
