An Amplified Offset Compensation Scheme and Its Application in a Track and Hold Circuit

This brief proposes a fully differential track and hold circuit using a new dc offset compensation scheme. It stores an amplified version of the offset during the hold phase, which is used in attenuated fashion during the track phase to compensate offset. This scheme is less sensitive to charge inje...
