A new technique using signal flow graph for
conversion of ladder based filter into CFOA based filter has been
proposed. The proposed technique converts the existing LC ladder based
filter into CFOA in low pass and high pass configuration. The design of
low pass filter and high pass filter has been realized using the
proposed technique. The proposed configuration is implemented using CFOA
as an active device and all the capacitors are grounded. Simulation has
been carried out using simulation software I-cap. The simulation
results have been demonstrated and discussed.
