Compact on-chip 60 GHz resonator with ring defected ground structure for millimetre-wave applications

摘要

This paper presents a design of a miniaturized resonator for millimeter-wave applications. The resonator is implemented in a standard 0.13μm (Bi)CMOS technology. Its performance is verified using an EM simulator from NI-AWR. The designed resonator is based on a unique structure, a combination of spiral loop and meander line structure. The ground plane is characteristically altered with a ring defected ground structure (DGS) to enhance the overall performance. The resonator design exhibits tuning flexibility at its resonance frequency within the mm-wave spectrum that is proportional to its design dimension. By using capacitive feeding, the designed resonator generates one transmission zero at 60 GHz with insertion loss of -2.7 dB and -29.4 dB return loss respectively. The chip size of the resonator excluding the pads is only 116 μm × 236 μm (0.027mm^2).
