A Broadside-coupled meander-line resonator (BCMLR) for ultra-compact millimeter-wave MMIC designs in 0.13μm SiGe technology

This paper proposed a novel broadside-coupled meander-line resonator (BCMLR) for millimeter-wave (mm-wave) passive and active circuit designs. This on-chip resonator is designed and fabricated using a 0.13μm SiGe technology. The proposed BCMLR consists of two broadside-coupled meander lines with opposite orientation. Applying this resonator with on-chip capacitors, a compact first-order and a second-order on-chip bandpass filters (BPFs) are designed. The measured results illustrate that the resonator can generate a resonance at 57 GHz with attenuation of 13.7 dB. The BCMLR based BPFs with excellent measured results are also presented in the paper as an example of applying the BCMLR in MMIC circuits designs. The chip size of both the BCMLR and the BPF, excluding the pads, is only 0.024 mm² (0.09 × 0.27mm²).3 page(s
