| Abstract: | The biquadratic variable delay equalizer with operational transconductance amplifiers (OTA) and capacitors (C) is presented. Its delay curve shape and maximum delay frequency can be adjusted by their respective controlled currents, and it can be conveniently integrated. The basic principle of biquadratic delay equalizer is analyzed, circuit structure of equalizer and the results of computer simulation are described in this paper. |
