Design of high-order active filters in integrated circuits

This correspondence considers the design of high-order filters using follow-the-leader feedback configurations and active-R biquadratic blocks. Statistical sensitivities of various second-order active-R and active-RC sections are compared, and experimental results of a sixth-order Butterworth bandpa...

Zusammenfassung:This correspondence considers the design of high-order filters using follow-the-leader feedback configurations and active-R biquadratic blocks. Statistical sensitivities of various second-order active-R and active-RC sections are compared, and experimental results of a sixth-order Butterworth bandpass filter are also included. The FLF configuration and versatile active-R blocks are also suitable for fully integrated filters.
