Performance Optimization of CNFET-based Domino Logic circuits
نویسنده
چکیده
-For many years VLSI Chip designers have been using Metal Oxide Semiconductor Field Effect Transistors (MOSFETs). As the channel length of device is reducing, effects like parametric variations and increase in leakage current have caused V-I characteristics to deviate from those of traditional MOSFETs. Hence the development of devices at deep submicron retards to some extent. Carbon Nanotube Field Effect transistors (CNFETs) is one of the most promising device for future Integrated Circuits. Most of the fundamental limitations of traditional MOSFETs are overcome in CNFETs. Domino Logic offers smaller area and higher speed than complementary CMOS design. In this paper circuit performance of CNFET based domino logic circuits is compared with conventional MOSFET. The design of OR, AND and Half adder using Domino Logic are Simulated in Subthreshold region under same channel length and different operational parameters. The main aim of the analysis is to show that the performance of CNFET based domino logic circuit is far better than conventional MOSFETs.

| Domino logic is a circuit family that is wellsuited to implementing high-speed circuits. Synthesis of domino circuits is more complex than static logic synthesis due to the non-inverting nature of the logic and the complex timing relationships associated with the clock scheme. In this paper, we address several problems along a domino synthesis ow. We mainly consider the problem of partitionin...
