A novel complex filter topology realized using current feedback operational amplifiers as active elements is introduced in this paper.\r\nOffered benefits are the low-voltage operation capability and the requirement for employing only grounded passive elements. Two\r\napplication examples are provided, where the frequency behavior of the derived filters fulfills the ZigBee and Bluetooth standards,\r\nrespectively. Their performance evaluation has been done through simulation results at postlayout level, using MOS transistor\r\nmodels provided by AMS C35B4 CMOS process.
