XDXMOS: a novel technique for the double-gate MOSFETs logic circuits - to achieve high drive current and small input capacitance together

A novel technique for the double-gate MOSFETs digital circuit, called cross-drive XMOS (XDXMOS), is proposed. Detailed mixed-mode circuit and device simulation results show that, with a simple addition of a register to the double-gate device in the 4-terminal operation mode, XDXMOS can achieve high drive current and small input capacitance together, and that 45% better power consumption performance and 25% better operation speed performance improvement over the conventional 3-terminal operation mode can be attained, while maintaining the ability for such useful techniques as the multiple-Vt method and the adaptive Vt control.
