Abstract

A 60GHz integrated second-order bandpass filter using rectangular open-loop resonators was designed and fabricated on a 0.13m standard CMOS process. The size of the filter is 415.5 × 502.8m2. The designed filter has a pair of transmission zeros at finite frequencies in the stopband, exhibiting good selectivity. The measured filter with the grid ground plane has a flat passband and its 1dB bandwidth is 9GHz (59.5-68.5GHz). The insertion loss is about 2.6dB and the return loss is better than 8.5dB across the passband. The effects of various ground configurations have been studied. The design was optimised with a new slotted ground plane, and its measurement shows a 1dB bandwidth of 9GHz (57-66..
