    Abstract
  • A new design method of switched-capacitor low-pass filter using signal-flow graphs and the general integrator is presented. The method is of simplicity, clear physical concept and convenience for use . It can also be applied easily to the design of other kinds of SCF(Switched-Capacitor Filter)(e.g. high-pass and band-pass etc). An example is given to show the design of a fifth-order ladder SCF,and the general-purpose circuits simulation programs Pspice5.0 is used to verify the design. It shows that the design method based on SFG(Signal Flow Graphs) and the general switched-capacitor integrator is efficient.
