  • A novel method for n-order current-mode filters using the Current Differencing Buffered Amplifier(CDBA) is presented. Based on the signal-flow-graph a systematic design formula is given in this papers. As examples, a new fifth-order butterworth low-pass, high-pass and fourth-order band-pass filters are realized. Simulation results from PSPICE are obtained to verify the theoretical analysis. The proposed filters have the characteristic of simple structure and less number of components.
