Abstract
Systems and methods for a track and hold amplifier with extended dynamic range may include a track amplifier comprising a first PMOS transistor coupled to a first NMOS transistor, a second PMOS transistor coupled to a second NMOS transistor, a capacitor at gates of each NMOS and PMOS transistor, and a plurality of switches. The track and hold amplifier is operable to, during a tracking mode of the track and hold amplifier, couple a differential input signal to each NMOS and PMOS transistor via a first switch coupled to a first capacitor coupled to the gate of the first PMOS transistor and a second capacitor coupled to the gate of the first NMOS transistor, and via a second switch coupled to a third capacitor coupled to the gate of the second PMOS and a fourth capacitor coupled to the gate of the second NMOS transistor.
