SENSE AMPLIFIER CIRCUIT, MEMORY CIRCUIT, AND SENSING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17846035 titled 'SENSE AMPLIFIER CIRCUIT, MEMORY CIRCUIT, AND SENSING METHOD THEREOF
Simplified Explanation
The abstract describes a sense amplifier circuit that includes a differential amplifier, two switches, and a control line. The differential amplifier amplifies the voltage difference between its output nodes based on the input voltages at its input nodes. The switches are connected to the input and output nodes of the differential amplifier and are controlled by a select signal on the control line. The switches pre-charge the input nodes using the output voltages of the amplifier.

Original Abstract Submitted
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.
