Today, the use of CMOS technology for the manufacture of electronic ICs has faced many limitations. Many alternatives to CMOS technology are offered and made every day. Quantum-dot cellular automata (QCA) is one of the most widely used. QCA gates and circuits have many advantages including small size, low power consumption and high speed. On the other hand, using special digital gates called re...

Using a level oriented model for verification of asynchronous circuits helps users to easily construct formal models with high readability or to naturally model data-path circuits. On the other hand, in order to use such a model for larger circuit, some technique to avoid the state explosion problem is essential. This paper first defines a level oriented formal model based on time Petri nets, a...

Evolvable hardware has been applied to the design of combinational logic circuits. But it usually takes too much time using evolutionary algorithm directly, especially designing large scale circuits. In this paper, a novel hybrid repair strategy is proposed, which is a combination of evolutionary repair method and Quine_McCluskey repair technique. Based on the hybrid repair strategy, an evoluti...

SPICE-compatible equivalent circuits were developed to facilitate the analysis and envelope simulation of electric circuits driven by modulated signals. The circuits are based on a novel complex phasor-domain transformation. The proposed method facilitates simulation of any general linear circuit driven by a modulated signal such as amplitude modulation, frequency modulation, or phase modulatio...

*Corresponding author Abstract SPICE compatible equivalent circuits were developed to facilitate the analysis and envelope simulation of electric circuits driven by modulated signals. The circuits are based on a novel complex phasor domain transformation. The proposed method facilitates simulation of any general linear circuit driven by a modulated signal such as AM, FM or PM. Simulation time b...

Neuromorphic circuits are being used to develop a new generation of computing technologies based on the organizing principles of the biological nervous system. Within this context, we present neuromorphic circuits for implementing massively parallel VLSI networks of integrate-and-fire neurons with adaptation and spike-based plasticity mechanisms. We describe both analog continuous time and digi...
