A　miniaturized　broadband　on-chip　bandpass　filter　(BPF)　is　presented　based　on　shunt　dual-layer　meander-line　resonators　and　several　metal-insulator-metal　(MIM)　capacitors.　To　understand　the　operational　mechanism　of　the　proposed　BPF　structure,　it　is　analyzed　using　a　simplified　LC　equivalent　circuit　model　for　further　investigation　of　the　transmission　zeros　(TZs)　distributions.　To　validate　the　proposed　idea,　the　BPF　with　three　TZs　is　implemented　in　a　commercial　0.13-　\mu　\text{m}　SiGe　(Bi)-CMOS　process.　The　measured　results　show　that　the　BPF　has　a　center　frequency　at　18　GHz　with　a　very　broad　bandwidth　of　66.7%,　and　the　minimum　insertion　loss　within　the　passband　is　2.9　dB.　The　chip,　excluding　the　GSG　pads,　is　about　0.318　mm　\times0.392　mm.　©　1980-2012　IEEE.
