“…As illustrated in Figure , the proposed balun BPF has exhibited good balanced performance in both simulation and measurement, and it has an amplitude imbalance better than 0.08 dB and a phase imbalance better than 4.9° over a wide band frequency range. Herein, it should be pointed out that the proposed wideband balun can be alternatively implemented on coplanar stripline (CPS), LTCC substrate, IPD‐, and IC‐based solutions …”

Wideband balun filter on slot‐line resonator with intrinsic balanced performance in magnitude and phase

Feng

2018

In this article, a novel wideband balun filter on the coupled slotline‐line resonator topology with intrinsic balanced performance in magnitude and phase performance is presented. The proposed wideband balun filter consists of four uniform half‐wavelength slot‐line resonators (SLRs) in middle, one single‐ended unbalanced port, and one balanced port with two terminals. By utilizing the distinct field conversion from the slotline to the microstrip line feeding line, the proposed technique can realize good balanced performance inherently in magnitude and phase over a wideband frequency range. In order to demonstrate the proposed scheme and support the design conception, one circuit prototype is designed, fabricated, and tested. All of the measured results of the frequency response, magnitude, and phase imbalance performance agree well with the simulated one, and these results have effectively demonstrated its good filtering property, intrinsic balanced performance in magnitude and phase over a wide band frequency.

“…However, a slow-wave structure is adopted for a design, the footprint of a passive component operating below 60 GHz is still fairly large. To solve this issue, a hybrid approach that utilizes capacitive-loaded TLs or INDs has been extensively used in [21]- [26] Since metal-insulator-metal (MIM) layer is provided for the most RF-CMOS process and MIM capacitor can be implemented in a very compact way, a combination of using a relatively large capacitance with a small inductance to obtain the required resonant frequency is desirable.…”

In this work, a new type of miniaturized on-chip resonator using coupled-inductor structure is presented. The impact on resonances of the structure due to the use of noninverting-and inverting-coupled configuration is extensively investigated. It has been found that using the inverting-coupled structure, a stronger resonance can be generated, which is ideally suitable for device miniaturization. To fully understand the working mechanism of the resonator and use it effectively for bandpass filter (BPF) design, simplified LC equivalent-circuit models and detailed theoretical analysis are provided. To further demonstrate the proposed concept is useful in practice, not only a 1 st-order BPF, but also another two 2 nd-order BPFs are designed and fabricated in a standard 0.13-µm (Bi)-CMOS technology. All of them are designed to have a centre frequency around 15 GHz. Their physical dimensions are 0.13 × 0.25 mm 2 , 0.26 × 0.25 mm 2 , 0.24 × 0.22 mm 2 , respectively. Good agreements between simulation and measurement have been obtained, which verify that the presented design approach is suitable for miniaturized on-chip passive design.
