  • A Low Power, 3.5-20GHz Tunable LNA with Out-Of-Band Blocker Filtering Based on Compact, Tunable Transmission Line (CTTL) Resonators in 65nm CMOS
Title: A Low Power, 3.5-20GHz Tunable LNA with Out-Of-Band Blocker Filtering Based on Compact, Tunable Transmission Line (CTTL) Resonators in 65nm CMOS
We present a tunable LNA for software defined radio based on a compact, tunable transmission line (CTTL) element. The CTTL acts as a passive, widely tunable LC resonance in a cascoded, common source LNA to implement an instantaneously narrowband, multi-octave tunable LNA. The resulting circuit, fabricated in 65nm CMOS, is tunable from 3.5-20GHz, and consumes 12 mW with gain >12dB, ≥ -9.6dBV in-band OP1dB, and OOB B1dB up to 31dB higher than the in-band B1dB due to the CTTL-tuned LC filtering. The CTTL-tuned LNA represents a more blocker-tolerant approach to achieving high frequency, software-defined LNAs without significant compromises in other LNA performance metrics.  more » « less

    Bistable liquid crystal (LC) shutters have attracted much interest due to their low energy consumption and fast response time. In this paper, we demonstrate an electrically tunable/switchable biostable LC light shutter in biological optics through a three–step easy–assembly, inexpensive, multi–channel shutter. The liquid crystal exhibits tunable transparency (100% to 10% compared to the initial light intensity) under different voltages (0 V to 90 V), indicating its tunable potential. By using biomedical images, the response time, resolution, and light intensity changes of the LC under different voltages in three common fluorescence wavelengths are displayed intuitively. Particularly, the shutter’s performance in tumor images under the near–infrared band shows its application potential in biomedical imaging fields.

    This paper presents a new continually-stepped variable gain low-noise-amplifier (CSVG-LNA) for millimeter-wave (mm-wave) 5G communications. The proposed variable-gain functionality in a two-stage LNA is achieved by incorporating a tunable-transformer at the 2nd-stage. The tunability in coupling-coefficient of the transformer allows to change the output matching of the LNA in a continuous fashion thus enabling a design of CSVG-LNA. The proposed CSVG-LNA alleviates high power consumption and large noise-figure (NF) variation problems in traditional approaches. To validate the proposed idea, we fabricated a CSVG-LNA in 65-nm CMOS process. The CSVG-LNA achieves measured 6.2dB of gain-tunability range while producing 18.2dB of peak S21 and <;4.1dB of NF 28GHz. Further, the NF variation is only ~0.2dB across the entire 6.2dB gain-tuning range. The 3dB bandwidth of CSVG-LNA is about 12GHz (22-34GHz) while it consumes only 9.8mW of dc power. The CSVG-LNA occupies a compact core area of 0.2mm2. The proposed CSVG-LNA achieves 1.5X improvement in FoM in comparison to state-of-the-arts mm-wave variable-gain CMOS LNAs.

    null (Ed.)
    Here we present a combined RF hardware/DSP technique to synthesize effective channel diversity in single-antenna wireless systems. This allows digital suppression of out-of-band interference artifacts in widely tunable wireless receivers with one or more antennas, including artifacts from LO phase noise. A passive inductor-capacitor (LC) network provides gain and phase diversity between channels and across frequency. Since amplitude and phase of in-band artifacts are set by the amplitude and phase of the out-of-band interference that generates them, they can be suppressed in DSP without knowledge about the interferer itself. The feasibility of this approach is demonstrated mathematically, with numerical system simulations, and full circuit simulation.

    Abstract Moiré superlattices created by the twisted stacking of two-dimensional crystals can host electronic bands with flat energy dispersion in which enhanced interactions promote correlated electron states. The twisted double bilayer graphene (TDBG), where two Bernal bilayer graphene are stacked with a twist angle, is such a moiré system with tunable flat bands. Here, we use gate-tuned scanning tunneling spectroscopy to directly demonstrate the tunability of the band structure of TDBG with an electric field and to show spectroscopic signatures of electronic correlations and topology for its flat band. Our spectroscopic experiments are in agreement with a continuum model of TDBG band structure and reveal signatures of a correlated insulator gap at partial filling of its isolated flat band. The topological properties of this flat band are probed with the application of a magnetic field, which leads to valley polarization and the splitting of Chern bands with a large effective g-factor.

    In this paper, we theoretically demonstrate a dual-band independently tunable absorber consisting of a stacked graphene nanodisk and graphene layer with nanohole structure, and a metal reflector spaced by insulator layers. This structure exhibits a dipole resonance mode in graphene nanodisks and a quadrupole resonance mode in the graphene layer with nanoholes, which results in the enhancement of absorption over a wide range of incident angles for both TE and TM polarizations. The peak absorption wavelength is analyzed in detail for different geometrical parameters and the Fermi energy levels of graphene. The results show that both peaks of the absorber can be tuned dynamically and simultaneously by varying the Fermi energy level of graphene nanodisks and graphene layer with nanoholes structure. In addition, one can also independently tune each resonant frequency by only changing the Fermi energy level of one graphene layer. Such a device could be used as a chemical sensor, detector or multi-band absorber.
