Abstract
A general purpose sense amplifier, suited for memory and level shifting applications, is provided. The present invention provides a high input impedence for less loading of bit line voltages, wherein operation is relatively insensitive to capacitive mismatches on input bit line pairs. Inherent in the high input impedence design is the built-in isolation between input and output circuitry. The present invention also provides a full rail to rail separation of the output bit line voltages without requiring additional pull-up or pull-down circuitry. The present invention also provides a single strobing input for activating and deactivating the sense amplifier. The present invention also provides minimal circuitry with high speed characteristics and low power dissipation.
