Abstract: A flip-flop element is configured to include FinFET technology transistors with a mix of threshold voltage levels. The data input path includes FinFET transistors configured with high voltage thresholds (HVT). The clock input path includes transistors configured with standard voltage thresholds (SVT). By including FinFET transistors with SVT thresholds in the clock signal path, the Miller capacitance of the clock signal path is reduced relative to HVT FinFET transistors, leading to lower rise time and correspondingly lower hold time. By including HVT threshold devices in the data input path, the flip-flop element attains high speed and low power operation. By including SVT threshold devices in the clock signal path, the flip-flop element achieves faster switching times in the clock signal path.
