| Abstract: | A novel high-performance first-order all-pass filter employing a single active element and a minimum number of passive components is presented. The proposed circuit is based on differential difference amplifier and is very suitable for low voltage operation. Also, the use of grounded capacitor enables its implementation with standard CMOS technologies. SPICE simulation and experimental results verifying theoretical analyses are also provided. |
