  • Negative capacitance logic device, clock generator including the same and method of operating clock generator
    Patent number: 9484924
    Abstract: A negative capacitance logic device includes a first field effect transistor (FET) and a second FET. The first FET is coupled between a power supply voltage and an output node, and the first FET includes a ferroelectric having a negative capacitance. The second FET is coupled between the output node and a ground voltage, and the second FET includes a ferroelectric having a negative capacitance. The negative capacitance logic differentiates an input voltage applied to an input node to provide an output voltage at the output node.
    Type: Grant
