Claim 14:
15. A sense amplifier, comprising:
a first stacked circuit of first, second, and third transistors coupled between first and second power supply terminals, wherein:
the first transistor includes a source terminal coupled to the first power supply terminal and a gate terminal coupled to a first input terminal for receiving a first input signal;
the second transistor is coupled between the first transistor and the third transistor; and
the third transistor is coupled between the second transistor and the second power supply terminal;

a second stacked circuit of fourth, fifth, and sixth transistors coupled between the first and second power supply terminals, wherein:
the fourth transistor includes a source terminal coupled to the first power terminal and a gate terminal coupled to a second input terminal for receiving a second input signal;
the fifth transistor is coupled between the fourth transistor and the sixth transistor; and
the sixth transistor is coupled between the fifth transistor and the second power supply terminal; and

an output circuit, coupled to the first and second stacked circuits, having an output terminal, and comprising third, fourth, fifth, and sixth stacked circuits each having three transistors, the third and fourth stacked circuits sharing a seventh stacked circuit of two transistors, the fifth and sixth stacked circuits sharing an eighth stacked circuit of two transistors.
