In this paper we present robust and high performance static ultra low-voltage CMOS binary logic. The delay of the ultra low-voltage logic presented are less than 10% of the delay of standard CMOS inverters. The logic gates presented are designed using semi floating-gate transistors and a current boost technique. The boolean gates resemble domino CMOS. The performance and robustness of different...

Molecular logic gates are capable of performing various logic tasks for biomarker detection, disease diagnostics and therapy, and controlling biological progress. Herein, we integrated multiple components of a logic device into a single DNA 3D nano-assembly with a triangular prism structure. Compared with the separate construction of each component in previously reported DNA logic gate systems,...

The CMOS based dual mode logic gates containing two operating modes: 1) static mode 2) dynamic modes. Features of dual mode logic gates are low power dissipation in static mode and high performance in dynamic mode. This methodology is used to minimize the delay and improve the speed of the logic gates and an additional clocked transistor is used in this methodology. It provides the very high le...

The novel 2xVDD NOT, NAND, and NOR logic gates have been designed and implemented in a nanoscale CMOS process with only 1xVDD devices. With the proposed dynamic source bias technique, the logic gates can be designed to have 2xVDD tolerant capability. Thus, the new 2xVDD logic gates can be operated under 2xVDD voltage environment without suffering the gate-oxide reliability issue.

Quantum cellular automata (QCA) enables performing arithmetic and logic operations at the molecular scale. This nanotechnology promises high device density, low power consumption and high computational power. Unlike the CMOS technology where the ON and OFF states of the transistors represent binary information, in QCA, data is represented by the charge configuration. The primary and basic devic...

Integration by parts: advanced information processing at the molecular level requires integrated logic gates, which has to date been possible only virtually. Now, two independently working AND molecular logic gates are brought together by "click" chemistry to form integrated logic gates which respond exactly as predicted from such an integration scheme.
