ABSTRACT:
A sense amplifier configured to amplify and output complementary input signals, comprising: a pair of first and second transistors; a pair of first and second resistor elements which are connected to at least one of source terminals and drain terminals of the first and second transistors, and pass electric current corresponding to a difference between threshold voltages of the first and second transistors; and an output terminal which is connected to a terminal different from the terminal to which the first and second resistor elements are connected, among the source terminal and the drain terminal of the first and second transistors, or which is connected to an end different from an end to which the source terminal and the drain terminal of the first and second transistors are connected, among both the ends of the first and second resistor elements.
