Patent ID: 7482843

Claim:
A signal amplifier comprising: first and second inverters, an input of said first inverter being connected to an output of the second inverter and an output of said first inverter being connected to an input of the second inverter, thereby forming a flip-flop; a control terminal of at least one transistor of first transistor pair constituting said first inverter, being connected through first capacitance to the input of said first inverter; a control terminal of at least one transistor of second transistor pair constituting said second inverter, being connected through second capacitance to the input of said second inverter; at a time of resetting, with the inputs and outputs of said first and second inverters being not mutually cross-connected, the inputs of said first and second inverters receiving a reference signal in common, said one transistors of said first and second transistor pairs being diode-connected, voltage differences between the reference signal and said respective control terminals of said one transistors being stored in said first capacitance and second capacitance, respectively; and at a time of signal input, the inputs of said first and second inverters being disconnected from the reference signal, the diode connections of said one transistors being released, the inputs of said first and second inverters receiving first and second input signals, respectively, and then the inputs and outputs of said first and second inverters being mutually cross-connected, thereby forming said flip-flop.
