| Abstract: | A new voltage-mode universal biquad filter circuit using current-feedback operational amplifiers(CFOA) was presented.The circuit consisted of four CFOA,two capacitors and ten resistors which achieved all the five filter functions,such as low-pass,band-pass,high-pass,notch,and all-pass from the same configuration.Circuit implementation was given and a computer simulation of the circuit was completed.PSPICE simulation results show that the design of circuit has the characteristics of simple structure and low sensitivity.All the capacitors are grounded and the filter is suitable for fully integration. |
