چکیده
In this paper we present novel ultra-low-voltage and high-speed CMOS NAND and NOR gates. For supply voltages below 500mV the delay for an ultra-low-voltage NAND2 gate is approximately 10% of a complementary CMOS inverter. Furthermore, the delay variations due to mismatch are much lesser than for conventional CMOS. Differential domino gates for AND2/NAND2 and OR2/NOR2 operation are presented. Ultra-low-voltage pass transistors are presented which can be used as latching gates. The ultra-low-voltage gates presented are going to be used for implementation of low-voltage and high speed adders. Keywords-Low-Voltage, High-Speed, NAND2, NOR2, CMOS, Floating-Gate
