The problem of sizing gates for power-delay tradeo s is of great interest to designers. In this work, the theoretical basis for gate sizing under delay and power considerations is presented, and results on a practical implementation are presented. The dynamic power as well as the short-circuit power are modeled, using notions of delay and transition density, and the optimization problem is form...

An analog QRS complex detection circuit, for pacemaker applications, based on the Wavelet Transform (WT) is presented here. The system detects the modulus maxima of the QRS complex. It consists of a wavelet transform fi lter, an absolute value circuit, a peak detector and a comparator. In order to achieve the low -power requirement in pacemakers, we propose a new method for implementing the WT ...

A software organization of a new circuit simulator, SAMOC (Switchedcapacitor Analysis of MOs Circuit) is presented in this paper. SAMOC employs extremely simplified, piecewise linear, resistive models to represent the semiconductor devices such as MOS transistors and ideal diodes in the simulated circuits. SAMOC also supports ideal switches and ideal capacitors for analyzing switched-capacitor ...

Complex responses, including chaotic responses, were observed through physiological experiments with biological neurons. To include these complex responses, the chaotic neuron model was proposed. Chaotic dynamical systems have been applied to logical systems, and to information and signal processing systems. In this paper, we propose a dynamic logic element with a chaotic transition region usin...
