Design of MOS Current Mode Logic Gates – Computing the Limits of Voltage Swing and Bias Current

2005

Minimizing a quality metric for an MCML gate, such as power-delay product or energy-delay product, requires solving a system of nonlinear equations subject to constraints on both bias current and voltage swing. In this paper, we will show that the limits of the swing and the bias current are affected by the constraints on maximum area and maximum delay. Moreover, methods for computing such limits are presented.

Novel high-performance QCA Fredkin gate and designing scalable QCA binary to gray and vice versa

2022

AbstractIn the design of digital logic circuits, QCA technology is an excellent alternative to CMOS technology. Its advantages over CMOS include low power consumption, fast circuit switching, and nanoscale design. Circuits that convert data between different formats are code converters. Code converters have an essential role in high-performance computing and signal processing. In this paper, first, we proposed a novel QCA structure for the quantum reversible Fredkin gate. Second, we proposed 4-bit and 8-bit QCA binary-to-gray converter and vice versa. For the second proposal, both reversible and irreversible structures are suggested. The proposed structures are scalable up to N bits. To cha…

Creativity by copying: imitating life as a work of imagination

2021

Engineering biological systems is easily interpretable as a process of mere and cold replication, or even distortion, of the natural domain, since it is often linked to industry and built on the Cartesian assumption of human rationality’s control over asubmissive nature. In this article, I approach living systems design from an alternative perspective, supporting its similarities with activities which are traditionally associated with creativity, like arts. I show that different kinds of creativity are deeply involved in copying, composing, and modifying life, focusing on two different levels: that of scientific modelling, recognisable by looking at biological circuits design, and that of a…
