The proposed LNA achieves its multi-band performance by employing a T-type matching topology as inter-stage matching network (IMN). The LNA has a measured gain of 14.5 dB and 14.1 dB, and simulated noise Figure (NF) of 2.4 dB and 3.4 dB at 28 and 60 GHz with a mean NF of 2.9 dB. The input return loss is less than -10 dB from 22-67 GHz. The chip occupies an area of 0.15 mm2t and consumes 27 mW from a 2.5 V power supply. To the authors’ knowledge the realized LNA is superior than any state-of-the-art LNAs in similar silicon technologies.","PeriodicalId":228725,"journal":{"name":"2019 14th European Microwave Integrated Circuits Conference (EuMIC)","volume":"208 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130976337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work is the first time using the double-transformer-coupling technique to achieve a wideband design. The major difference between proposed and traditional wideband LNA is the use of double-transformer-coupling technique and T-type matching method to control the upper/lower 3-dB frequencies. In addition, the combination of double transformer and current re-used technique not only can save dc power and die area but also can implement the gm-boost technique to improve the overall transconductance. The peak gain of LNA is 21.6 dB and has a fractional 3-dB bandwidth of 35.2 % which is from 46.5 to 65.8 GHz. Across-frequency ranges from 50 to 66 GHz, the measured the N.F., IP1dB, and IIP3 are better than 7.28 dB, -21.6 dBm and -13.16 dBm, respectively. The total dc power consumption is only 16.3 mW for 1.2 V supply voltage. To our best knowledge, this LNA has the wider fractional bandwidth, lower dc power, more compact die area and excellent FoM at V-band among CMOS LNAs.","PeriodicalId":228725,"journal":{"name":"2019 14th European Microwave Integrated Circuits Conference (EuMIC)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115877608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To design a low-power DCO, minimising the loss of the LC tank is very critical. Hence, a high quality factor (Q) multifinger capacitor and a high-Q centre-tapped inductor are proposed and designed. Simulated Q of the capacitor is more than 45 from 70 GHz to 80 GHz. It is at least 4.5 times higher than a typical metal-insulator-metal capacitor (MIMCAP). The proposed DCO based on the designed high-Q passives is fabricated in standard 65 nm CMOS. Measured foSC are 74. 1GHz and 76.7 GHz in the on-and off-state of the switch, respectively. It consumes only 3.15 mW DC power from a supply of 0. 75V which to the authors’ knowledge is the lowest power consumption reported so far in this frequency range.","PeriodicalId":228725,"journal":{"name":"2019 14th European Microwave Integrated Circuits Conference (EuMIC)","volume":"564 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114988456","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Developing radio technologies that maximize data rate within a finite spectrum slice is a very important goal to such spectrum access businesses. This requires radios to provide high values of spectrum efficiency (bits per second per Hertz-bandwidth (bps/Hz)). This paper is the first to introduce a conventional Nyquist filtered 4096-QAM signal implemented with a switching-circuit based transmitter. Even by having no circuit linearity in the RF path and using polar modulation, the reported signal quality measurements confirm less than 0.9% error-vector magnitude for this 12 bps/Hz constellation. Signal ACLR is -54dB, peak output power is 2.5 watts, and the transmitter efficiency exceeds 50% when modulated and including all linearization power. The limits of using EVM as a signal quality metric are presented and discussed.","PeriodicalId":228725,"journal":{"name":"2019 14th European Microwave Integrated Circuits Conference (EuMIC)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116899484","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This behavior violates the law of energy conservation and impedes stability analysis of MMIC circuits, especially class C amplifiers. We circumvented this limitation by introducing a new modeling approach: energy-based capacitance modeling. Instead of modeling capacitances or charges, we model the electrical energy stored in the transistor. From this quantity we derive expressions for charges and capacitances by means of differentiation. We applied this approach to an LDMOS device and achieved very good accuracy, while maintaining charge and energy conservation.","PeriodicalId":228725,"journal":{"name":"2019 14th European Microwave Integrated Circuits Conference (EuMIC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127544873","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
