Analytical performance evaluation of molecular logic circuits

Abstract

The urgent need for high performance computing and low power consumption has forced researchers to think of alternative solutions to tackle this problem. As we know, by reducing the size of our electronic components, we can have the same functionality in smaller areas and this will lead to less power consumption. Nanoelectronics has been proposed as the solution in which we are facing devices in nanometer sizes. However, in the case of solid-state nanoelectronics, this process has become into an expensive and sophisticated solution. An alternative way is the use of molecular electronics which has advantages such as precision and low fabrication costs. There have been noticeable advances in the field of molecular wires, insulator, diodes, transistors and memories. In this paper, we present a method for evaluating the performance of molecular circuits. We analyze the performance of circuits in terms of occupied area, critical path length and power consumption and talk about some of the constraints facing the design. We also give an example in order to show our method of evaluation.

Designing and Modeling of Logic Circuits Based on Switching of the Gated Oligo-Phenylenevinylene Molecule

“…In the recent years, the scientists have found that, in comparison with technology based on silicon, molecules, as active electronic components for applications, provide region for nano-sized structures [1]. On the other hand, several designs of logic gates and logic circuits are based on the diode devices [2][3][4][5]. These are also featured disadvantages of the diode, such as high power consumption and low-speed of operation.…”
