A physical and electrical switched capacitor filter design environment

This paper presents a switched-capacitor filters design environment. The electrical design support is based on two simulators front public domain: Spice3f5 and Switcap. The physical design flow is based on a set of analog specific constraints for stack generation, placing and routing of analog blocks. A high-Q band-pass filter practical design example is presented in order to illustrate the ability of the environment to generate optimal analog building blocks with minimum time expense
