Two configurations for realizing higher-order series and parallel immittance functions using current conveyors are presented. The proposed circuits require only grounded resistors and capacitors. As examples of their applications, highpass and bandpass filters are given with simulation results.
We propose a systematic method to design band-pass filters composed of film bulk acoustic resonators (FBARs), for wireless communication. FBARs have demonstrated excellent performance due to their compact size, low loss, power endurance and IC compatibility. Modifying the traditional Butterworth theory, the ladder-type band-pass filters can be composed of FBARs to satisfy various filter specifications...
