This paper deals with the automated synthesis of open complementary split ring resonators (OCSRRs) using aggressive space mapping (ASM) for the first time. These open resonators are electrically small planar elements useful for the implementation of shunt LC resonators in microstrip or coplanar waveguide technology. However, their synthesis is in general complex and requires the experience of the...
This paper presents a novel compact, UHF-band lumped element filter that shows good results versus other similar designs, with a 20% fractional bandwidth operating at 500MHz with a 17dB return loss. The circuit was designed using multilayer LCP, with a focus on minimising the footprint and the number of vias present, which was achieved by folding the design and implementing a block of shared ground...
This paper presents a novel ultra-compact and lowinsertion loss 77-GHz on-chip bandpass filter (BPF) fabricated with a 0.18-µm standard CMOS process. The stepped-impedance resonators (SIRs) used in this filter allow for more freedom to adjust design parameters and yield a transmission zero at the right side of the passband. The other transmission zero is produced by two-path mechanism. The transmission...
