A switched capacitor filter synthesis system with built-in design for manufacturability

The paper presents a switched capacitor filter synthesis system with yield estimation and optimization as the integral components of the design environment. The design process is an iterative process involving filter synthesis and yield estimation. Different design choices such as filter order, approximation, circuit topology, etc., affect the yield and also other parameters such as filter area, noise and dynamic range. The integrated environment offers effective mechanisms for exploring the design decision space to achieve the optimum in terms of yield and other design considerations. The paper describes the filter synthesis, yield estimation and optimization aspects of the system. The capabilities offered in the areas of data and flow management are also discussed. The results for a low pass filter design are presented.<
