Patent abstract
A sense amplifier for a memory includes a transistor, an operational amplifier, and a compensating circuit. The negative input end of the operational amplifier is coupled to the compensating circuit. The positive input end of the operational amplifier is coupled to the drain of the transistor. The output end of the operational amplifier is coupled to the gate of the transistor. The compensating circuit is coupled between the negative input end and the output end of the operational amplifier. The compensating circuit generates a compensating voltage to the negative input end of the operational amplifier according to the voltage of the gate of the transistor.
