Abstract
The disclosure provides a sense amplifier and a control method thereof. The sense amplifier includes: a pre-charge module, a first input and output terminal, a second input and output terminal, a first PMOS transistor, a second PMOS transistor, a first NMOS transistor, and a second NMOS transistor, a first switch unit, a second switch unit, a third switch unit, a fourth switch unit, a fifth switch unit, a sixth switch unit, a seventh switch unit, an eighth switch unit, a first energy storage unit and a second energy storage unit. The sense amplifier can compensate for the offset voltage. The result is a sense amplifier with greatly reduced offset voltage, thereby improving the sensitivity and resolution of the sense amplifier.
