Both signals are multiplied using an on-chip low-noise, high linearity mixer to measure the real power delivered to the load of an integrated PA operating at $5mathrm {G}mathrm {H}mathrm {z}$ in predictive $45mathrm {n}mathrm {m}$ CMOS technology. The dynamic range of the detector is $23.~72mathrm {d}mathrm {B}$ with an accuracy of $< pm 0.5mathrm {d}mathrm {B}$. Even under antenna load mismatch the detector is able measure the real power delivered to the load up to a voltage standing wave ration of 2.7:1 with an error $< pm 0.6mathrm {d}mathrm {B}.$ The power detector has no effect on the PA performance and can be integrated under the large output matching transformer, resulting in a cost efficient design.","PeriodicalId":384458,"journal":{"name":"2018 14th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME)","volume":"295 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122091325","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}

The nonlinear characteristics are first analysed theoretically. This analysis reveals that the nonlinearity can be ‘neutralised’ by replacing the spring with a nonlinear - cubic stiffness - spring. Finding a feasible solution requires finding a compromise between a large number of geometric dimensions and constraints; this was achieved by making extensive use of MATLAB’s optimization toolbox. The device having optimal dimensions was manufactured using the SOIMUMPs process and lab measurements confirmed that the overall nonlinearity was practically eliminated for actuation voltages of 4 volts and upwards.","PeriodicalId":384458,"journal":{"name":"2018 14th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131697112","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}

The basic cell is synthesized in quasi-distributed form as the cascade of two single-FET stages. Whereas the operating principle of the overall TLA is well-known (i.e., cascading several hard-limiting cells), the topology of the proposed basic cell is not common. The broadband characteristics and the extreme compactness of the proposed architecture make it particularly suitable for the realization of multi-stage TLAs. The proposed basic cell is then adopted to design, as a test vehicle, a six-stages TLA, using a 0.25 μm GaN-on-SiC HEMT technology provided by UMS foundry. The final MMIC exhibits a broadband behavior, in the range 1.2 GHz-2.2 GHz, with a global logarithmic error of ±1 dB over 60 dB of input dynamic range (IDR).","PeriodicalId":384458,"journal":{"name":"2018 14th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME)","volume":"67 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127246348","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}
