Abstract
The sense amplifier circuit includes a differential amplifier, a first switch, and a second switch. The differential amplifier includes a first input node, a second input node, a first output node, and a second output node. The differential amplifier amplifies a voltage difference of the first output node and the second output node according to a first input voltage of the first input node and a second input voltage of the second input node. A control node of the first (second) switch is coupled to a control line, the first (second) switch is coupled to the first (second) input node, and the first (second) switch is coupled to the first (second) output node. The first (second) switch pre-charges the first (second) input node by a first (second) output voltage of the first (second) output node while the control line is received a select signal.
