all practical digital circuits are usually a mixture of combinational and sequential logic. flip–flops are essential to sequential logic therefore fuzzy flip–flops are considered to be among the most essential topics of fuzzy digital circuit. the concept of fuzzy digital circuit is among the most interesting applications of fuzzy sets and logic due to the fact that if there has to be an ultimat...

Due to the advanced fabrication technology, the oxide thickness is now in the regime of 1.0 nm for nanoscale MOSFETs. The quantization effects and inversion charge density displacement away from the interface of oxide and silicon can not be neglected. The most accurate model for such problem is solving the Schrödinger-Poisson (SP) equations with proper boundary condition in 1D structure. Howeve...

A generalization of the model of PWM (Pulse Width Modulation) switch according to Dijk et al. [1] for averaged modeling of switched DC-DC converters is proposed. The original model by Dijk consists of controlled current and voltage sources for modeling the ideal active and passive switch. A new model, proposed in this paper, is based on the same strategy, but it takes into account the nonideal ...

Techniques for analyzing the dynamic patterns of power flow in high frequency dc-dc switching converters are developed. Emphasis is placed on exploring methods for developing reduced order instantaneous and averaged models of power electronic circuits for simulation, analysis, and control design. Tools from selective modal analysis are used to develop the dynamic pattern recognition algorithm, ...

In this paper, the relationship between typical circuit structures of gas sensor circuits and their output noise is analyzed. By using averaged segmenting periodical graph and improved histogram estimation methods, we estimated their noise power spectra and optimal probability distribution functions (pdf). The results were confirmed through experiment studies.

David B. Kirk'" We have designed, fabricated, and tested an analog VLSI chip which computes radial basis functions in parallel. We have developed a synapse circuit that approximates a quadratic function. We aggregate these circuits to form radial basis functions. These radial basis functions are then averaged together using a follower aggregator.
