DISTRIBUTION CODE ABSTRACT (Maximum 200 words)The goal of this research contract was the development of CAD tools to compute statistical information (in particular, mean and variance) about the power dissipated in a continuous-time or switched-capacitor circuit, when statistical information about the input signals to the circuit is given. This approach mirrors the one generally used to estimate power dissipation in digital CMOS circuits. Two power estimation CAD programs were developed: one for continuous-time analog circuits, the other for switched-capacitor circuits. Those tools were integrated into an existing commercial CAD environment, namely CADENCE'S Design Framework II. SUBJECT TERMS

“…The number of contributions on linear time-varying discrete-time periodic systems has been increasing in recent times; see, e.g., [15,19,22,45,47,49] and the references therein. This increasing interest in periodic systems has also been motivated by the large variety of processes that can be modelled through linear discrete-time periodic systems (e.g., multirate sampled-data systems, chemical processes, periodically time-varying filters and networks, and seasonal phenomena [2,3,7,16,28,33,51]). …”

From the necessary and sufficient conditions for complete reachability and observability of periodic time-varying descriptor systems, the symmetric positive semi-definite reachability/observability Gramians are defined. These Gramians can be shown to satisfy some projected generalized discrete-time periodic Lyapunov equations. We propose a numerical method for solving these projected Lyapunov equations, and an illustrative numerical example is given. As an application of our results, the balanced realization of periodic descriptor systems is discussed.
