Abstract
The present disclosure provides a sense amplifier. The sense amplifier includes a first inverting circuit, a second inverting circuit, a pre-charge circuit, a voltage adjusting circuit, and a discharge circuit. The first inverting circuit has a first input end and a first output end, and the second inverting circuit has a second input end and a second output end. The pre-charge circuit pulls up the voltage levels on the first and second output ends according to a power voltage during a pre-charge time period. The voltage adjusting circuit respectively receives a bit line voltage and a reference voltage during the pre-charge time period, and adjusts voltages on the first and second output ends respectively according to the voltage on the second and first receiving ends. The discharge circuit pulls down voltage levels on the first and second receiving ends of the voltage adjusting circuit during a discharge time period.
