Patent ID: 10673435

Abstract:
A method and apparatus for reducing dynamic switching current in high speed logic. The apparatus may include a CMOS logic circuit, which in turn includes an NMOS FinFET, a first PMOS FinFET, and a second PMOS FinFET. A gate of the NMOS FinFET is connected to a gate of the first PMOS FinFET, a drain of the NMOS FinFET is connected to a drain of the first PMOS FinFET, and the second PMOS FinFET is connected to the first PMOS FinFET to create a capacitor between a source and the drain of the first PMOS FinFET. In one embodiment, the second PMOS FinFET is contained in and positioned at an edge of a cell that also contains the first PMOS FinFET and the NMOS FinFET.
