Abstract :
The authors present a computer program called MASFIL for the synthesis of switched-capacitor (SC) filters. MASFIL allows the user to synthesize filters with classic and nonclassic transfer functions. The program handles the nonclassic cases with an adaptive simulated annealing algorithm. The algorithm optimizes the transfer functions to satisfy the user-given frequency response and group delay specifications. MASFIL runs on an IBM/PC/AT and gives as output a hierarchical schematic and a netlist file. The main advantages of using MASFIL have been the drastic reduction in design time (from weeks to hours) and a more effective usage of silicon area because of the capability of implementing multirate switched capacitor filters with nonclassic transfer functions.<>
