Abstract
A semiconductor integrated circuit includes a sense amplifier for amplifying an input signal and a complement of the input signal. The sense amplifier includes cross-coupled transistors. Each unique cross-coupled transistor is coupled to a corresponding unique transistor formed as a diode. A resistor is coupled in series between one cross-coupled resistor and an input port receiving the input signal, and another resistor is coupled in series between the other cross-coupled transistor and another input port receiving the complement of the input signal. Resistances associated with the sources of each cross-coupled transistor provide the resistance of the resistors.
