Classification: CPC G | IPC G

Claim 0:
1. A sense amplifier circuit with temperature compensation, comprising:
a sense amplifier, including:
a first input end coupled to a target bit having high impedance in a first state and having low impedance in a second state, wherein the high impedance has a first temperature coefficient and the low impedance has a second temperature coefficient;
a second input end; and
an output end;

a first switch configured to operate according to a first control signal for providing reference impedance having a third temperature coefficient, and including:
a first end coupled to the second input end of the sense amplifier;
a second end; and
a control end for receiving the first control signal; and

a temperature compensation circuit coupled to the control end of the first switch and configured to provide the first control signal having a fourth temperature coefficient, wherein the first temperature coefficient, the second temperature coefficient and the third temperature coefficient have a same polarity, and the fourth temperature coefficient and the first temperature coefficient have opposite polarities.
