A 3-dB bandwidth of 19–34 GHz (56% fractional bandwidth) is obtained through the use of inductively degenerated SiGe HBTs with large emitter lengths. The detector achieves a minimum noise-equivalent power (NEP) of 0.49 pW/VHz at 24 GHz with a peak responsivity of 17.1 kV/W. Through careful transistor biasing and judicious use of resistors, the detector achieves a measured 1/f noise corner frequency of 24 Hz when biased for optimal NEP. To the best of our knowledge, this detector achieves the widest fractional bandwidth and best 1/f noise performance of all tuned transistor-based square-law detectors for high-frequency radiometers to date.","PeriodicalId":120932,"journal":{"name":"2017 12th European Microwave Integrated Circuits Conference (EuMIC)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130660259","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 paper addresses the question, how HEMT devices within a certain technology can be optimized only by changing basic geometrical properties. While epitaxial layer structure and gate length usually are not accessible, the circuit designer might be able to choose parameters as gate finger width and gate-source spacing. In this analysis, GaN HEMT samples were fabricated, measured and modeled. The layout of the devices was varied in order to study possibilities to improve noise figure. It is shown that significant improvements in noise performance are to be expected by optimizing gate finger width, while the slight improvement in terms of noise figure resulting from a reduction in gate-source spacing compromises gate breakdown and should be avoided. This work provides the designer of low-noise amplifier MMICs with a qualitative analysis and quantitative examples of a state-of-the art GaN HEMT process how to optimize the layout of the HEMT for low-noise and highly rugged LNA design.","PeriodicalId":120932,"journal":{"name":"2017 12th European Microwave Integrated Circuits Conference (EuMIC)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134278147","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 paper focuses on the receiver architecture for demodulation of the Q-PPM IR signal. The principle and a detailed analysis of the demodulation scheme are described. The integrated receiver chip was developed in 55-nm CMOS technology. It includes all circuit blocks based on the proposed demodulation architecture, which consists of an in-phase/quadrature (IQ) demodulator, a symbol clock recovery circuit, and a local impulse generator.

Wirtinger calculus is applied to a non-analytic X-parameter expression to formulate the extremal problem in a form that can be solved exactly, by hand, in explicit form. Compact formulas for the exact solution are valid for small and large input drive levels and small-to-moderate output mismatch, and reduce to the well-known S-parameter result in the small-signal limit. The results are validated numerically and against measured load-pull data on a commercial power amplifier. The method enables a fast, prescriptive, X-parameter based production test for a key large-signal PA figure of merit, beyond what is possible from S-parameters, and without the need for searching the measured performance space.","PeriodicalId":120932,"journal":{"name":"2017 12th European Microwave Integrated Circuits Conference (EuMIC)","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124681899","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}
