Persistent neural firing is of fundamental importance to working memory and other brain functions because it allows information to be held "online" following an input and to be integrated over time. Many models of persistent activity rely on some kind of positive feedback internal to the neural circuit concerned; however, too much feedback causes runaway firing (instability), and too little res...

The combined effects of deviation from ideal in integrator upon the characteristics of the integrators. Inverting and noninverting magnitude and phase on the performance of integrator-based active filters integrators for use in active filters which are independent of first-order and is investigated. The limitations of using the integrator Q-factor as a second-order operational amplifier time co...

The subject of controlling an integrator via a communication network finds many applications in modern control systems. Stability conditions in closed form are derived for the arising feedback system, which consists of a controller, an integrator and time-variant links between integrator and controller. It will be shown, that these derived stability conditions are not conservative and easily ap...

In this paper we study the performance of a symplectic numerical integrator based on the splitting method. This method is applied to a subtle problem i.e. higher order resonance of the elastic pendulum. In order to numerically study the phase space of the elastic pendulum at higher order resonance, a numerical integrator which preserves qualitative features after long integration times is neede...

We present an unexampled reset integrator control design based on the Clegg integrator system. Using an appropriate mathematical model of our Clegg integrator controller, stability proof of the closed-loop system applied to the vibration control problem of a second-order system is shown without invoking hybrid system theory. Furthermore, we illustrate the applicability of our controller, from t...

In real-world applications, controllers must operate in the presence of an untold number of off-nominal conditions that either were not or could not be accounted for during formal synthesis. Engineers compensate for these real-world effects by extensive simulation and testing. Only after extensive evaluation and validation can a controller be accepted for critical applications. In addition, it ...

The recent explosion of interest in wireless personal communication systems motivates the development of fully integrated radio receivers. The parallel reduction of the dimension in CMOS technology, and hence higher levels of integration enables the combined integration of bandpass or baseband analog-to-digital converter along with the traditional front-end receiver building blocks. While this ...
