| Abstract: | Based on CFTA,a grounded and a floating simulated inductance circuits were proposed.The circuits employed grounded capacitor,minimum number of active components and its input and output terminals.To confirm the reliability of the circuits,based on inductance circuits,component substitution method was used to design Butterworth third-order low-pass and high-pass filter respectively,its Pole frequency fo=100 kHz and pass-band gain Aup=0.5.The computer simulation results indicated that the proposed circuits were valid and effective. |
