This paper describes a general method for the synthesis of SAW filters based on the composition of basic structure elements and variation of electrode lengths. Optimization algorithm using the scanning window approach allows effective synthesis or improvement of responses for different types of filters. The realizability and adequacy of the synthesis results were improved because the topology constraints...
A description is given of a novel hierarchical timing assignment method, for the transistor sizing of multistage MOS circuits. The approach is composed of two steps: the first is the optimal timing assignments to logic stages in possible logical paths; and the second is the optimization of the sizes of all the transistors in each stage to realize the timing assignments. Compared with unsized circuits,...
