Consider a directed graph G in which every edge has an associated real-valued distance and a real-valued weight. The weight of an undirected circuit of G is the sum of the weights of the edges, whereas the distance of an undirected circuit is the sum of the distances of the forward edges of the circuit minus the sum of the distances of the backward edges. A trivial circuit is a two-edge circuit...

In order to accurately analyze the dynamic characteristics of the vacuum circuit breaker, a dual-core master-slave processor structure for online monitoring system based on DSP and ARM is proposed. This structure consists of host computer, lower computer and signal processing modules. The lower computer uses DSP as the core, which completes acquisition and data preprocessing of circuit breaker’...

Students studying undergraduate courses in digital electronics often lose interest in the subject, due to the short comings of learning tools that are commonly used to supplement such courses. Ideally learning tools increase student participation in the learning process and help in overcoming difficulties inherent to the subject. Comparisons have been drawn between the existing learning tools. ...

Existing power estimation techniques at the gate level and the circuit level can be classi ed into two classes static and dynamic Static techniques rely on statistical information such as the mean activity of the input signals and their correlations about the input stream to estimate the internal switching activity of the circuit While these are very e cient their main limitation is that they c...

The dynamic and short-circuit power consumption of a complementary metal–oxide–semidconductor (CMOS) gate driving an inductance–capacitance (LC) transmission line as a limiting case of an RLC transmission line is investigated in this paper. Closed-form solutions for the output voltage and shortcircuit power of a CMOS gate driving an LC transmission line are presented. A closed form solution for...

OF THE DISSERTATION A Novel Dynamic Power Cutoff Technology (DPCT) for Active Leakage Reduction in Deep Submicron VLSI CMOS Circuits by Baozhen Yu Dissertation Director: Prof. Michael L. Bushnell Due to the exponential increase of subthreshold and gate leakage currents with technology scaling, leakage power is increasingly significant in CMOS circuits as the technology scales down. The leakage ...

Circuit Breakers (CBs) are critical components in power system for reliability and protection. To assure their accurate performance, a comprehensive condition assessment is of an imminent importance. Based on dynamic resistance measurement (DRM), this paper discusses a simple yet effective fuzzy approach for evaluating CB’s electrical contacts condition. According to 300 test results obta...

A continuous-time common-mode feedback circuit (CMFB) is presented. A two-stage high-gain architecture is used to minimize the offset of the common-mode voltage. A special compensation scheme enables this circuit to be used in high-impedance current-mode systems without a stability problem. Simulation and testing results show the superior performance of this circuit. It is proven to be an ideal...

This paper describes a design approach to Lorentz motors that serve as active damping component applicable in dynamic vibration isolators used for integrated circuit(IC) equipments. To satisfy the demand of high force density in constrained space and high current accuracy of motor drive for active damping, an analytical layer model with proper simplifications is employed to get preliminary dime...

Abstract—We propose an analog integrated circuit that implements a resonate-and-fire neuron (RFN) model based on the Volterra system. The RFN model is a simple spiking neuron model that exhibits dynamic behavior observed in biological neurons, such as fast subthreshold oscillation, post-inhibitory rebound, and frequency preference. The RFN circuit was derived from the Volterra system to mimic s...
