Abstract—Today’s modern interconnected power system is highly complex in nature. In this, one of the most important requirements during the operation of the electric power system is the reliability and security. Power and frequency oscillation damping mechanism improve the reliability. Because of power system stabilizer (PSS) low speed response against of major fault such as three phase short c...

The operational amplifier (op amp) is one of the most encountered analog building blocks. In this paper, the problem of testing an integrated op amp is treated. A new low-cost vectorless test solution, known as oscillation test, is investigated to test the op amp. During the test mode, the op amps are converted to a circuit that oscillates and the oscillation frequency is evaluated to monitor f...

This article proposes a highly efficient Time-Based Maximum-Power-Point-Tracking (TB-MPPT) integrated-circuit. Conventional TB-MPPT circuit shows unstable status (oscillation) near the Maximum Power Point (MPP), which causes degradation of overall power tracking efficiency. To overcome this critical issue, proposed separates operation into two periods, and it utilizes convergence range averagin...

The light output of quantum cascade lasers is strongly affected by electric field-domain oscillations if the laser shows electrical instabilities. This can result in a substantial broadening emission spectrum, which investigated here detailed simulations for terahertz device. We explain how pulsation injection conditions and external capacitances. Experimental data confirm that oscillation freq...

This paper describes a test structure consisting of a ring oscillator and an inverter chain. The load of the elements of the ring oscillator and the inverter chain is programmable.

-The present paper reports a first order nonlinear retarded type time-delayed chaotic and hyperchaotic electronic circuit. The proposed circuit has three distinct advantages over the existing time-delayed circuits. First, it has a nonlinearity that is expressed by closed form mathematical functions, which makes the analysis and design of the circuit easier. Second, the time-delay part of the pr...

The dynamic process of differentiation depends on the architecture, quantitative parameters, and noise of underlying genetic circuits. However, it remains unclear how these elements combine to control cellular behavior. We analyzed the probabilistic and transient differentiation of Bacillus subtilis cells into the state of competence. A few key parameters independently tuned the frequency of in...

We study the nonlinear dynamical behavior of a semiconductor laser subject to delayed optoelectronic feedback. We perform this study by designing a simple electronic circuit whose behavior is governed by the same equations that govern the laser system. The circuit offers important experimental advantages, since it operates with much slower speeds, and has easily tunable parameters. Furthermore,...
