Hysteresis reduced sense amplifier and method of operation

摘要

A sense amplifier (40) uses a body shorting device (60) to selectively electrically short circuit the bodies of two transistors (44, 48) that function as a differential sensing pair. Equalization of charge injected into the bodies functions to minimize offset voltage between the two bodies. The body shorting device selectively shorts the bodies in response to a body control signal after a sense operation and after asserting a precharging signal to initiate precharging of the sense amplifier's outputs.
