Patent ID: 7304903

Claim:
A sense amplifier circuit comprising: a first double-gate MOSFET (DGMOSFET) having a first gate defining a first input to the circuit, a second gate and an output being coupled to a first output of the circuit; and a second DGMOSFET having a first gate defining a second input of the circuit, a second gate connected to the output of the first DGMOSFET and an output connected to the second gate of the first DGMOSFET, the output of the second DGMOSFET being coupled to a second output of the circuit; a third DGMOSFET having a first and second gates connected to the second gate of the first DGMOSFET and coupled to the second output of the circuit, an input configured to be connected to a voltage supply, and an output coupled to the first output of the circuit; and a fourth DGMOSFET having first and second gates connected to the second gate of the second DGMOSFET and coupled to the first output of the circuit, an input configured to be connected to a voltage supply, and an output coupled to the second output of the circuit.
