The power amplifier is adopting a tuning capacitor in parallel with the choke inductor, which reduces the DC power consumption of the inductor and decreases the chip size. The total power added efficiency (PAE) is enhanced as a result. The proposed power amplifier is manufactured using a 0.25 μm SiGe hetero-junction bipolar transistor (HBT) process. For a LTE signal with a centre frequency of 2.1 GHz, the PA delivers an output power of 21.3 dBm with the power added efficiency (PAE) of 21% and power gain of 19.5 dB at the 1 dB compression point. For the LTE downlink quadrature amplitude modulation (QAM64) signal at 2.11 GHz with 20 MHz channel bandwidth, the measured ACLR is below -30 dBc for the output power of 18 dBm with PAE above 15%. The error vector magnitude (EVM) specifications are met for LTE 20 MHz bandwidth QPSK modulation scheme, and complied with 1 dB power back-off for QAM16 signal and at 2 dB power back-off for QAM64 modulation scheme. The measurement results verify that the proposed method is promising for the application of the fully integrated PA.","PeriodicalId":125553,"journal":{"name":"Proceedings of the 2013 9th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121451155","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 energy needed for the described power-expensive operations is obtained by charging a buffer capacitor while the system is in a low-power-consumption state. A voltage level detector senses the charging status of the capacitor and wakes-up the sensing station every time enough energy is stored. Thus, the environmental parameters are monitorized and transmitted with an asynchronous and intermittent strategy. The optimization work related to this paper has persued the target of minimize the unerasable continuous power consumption of the voltage detector during the charging of the capacitor. We reached the goal of reducing it from the 50 μW of the previous version of the system to the current 5 μW, with a significant usability improvement. Simulations and experimental evidences demonstrate that our station can work totally battery-free when just illuminated with 100 W/m2 of light irradiance, transmitting data with a 802.15.4 compliant protocol and potentially occupies a volume of 1 cm3.","PeriodicalId":125553,"journal":{"name":"Proceedings of the 2013 9th Conference on Ph.D. Research in Microelectronics and Electronics (PRIME)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121908430","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}
