Auto-SC, an automated switched-capacitor ladder filter design program

摘要

The use of a switched-capacitor filter design program, Auto-SC, is discussed. The program can be used to design both single-ended and differential switched-capacitor filters by a number of different methods. Guidelines for designing switched-capacitor filters using Auto-SC are presented. The circuits designed by Auto-SC are in a format that is directly compatible with SWITCAP. A design example is included.
