2. 1. RF Wireless Power Transfer for IoT Applications

   Author : Morteza Tavana; Emil Björnson; Jens Zander; Ayça Özçelikkale; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronic waste; Energy harvesting; Internet of things; transceivers; wireless power transfer; wireless sensor networks; Informations- och kommunikationsteknik; Information and Communication Technology;

   Abstract : With the emergence of the Internet of things (IoT) networks, the replacement of batteries for IoT devices became challenging. In particular, the battery replacement is more expensive and cumbersome for scenarios where there are many IoT devices; or where the IoT devices are in unreachable locations; or when they have to be replaced often.

4. 2. Efficient Integrated Circuits for Wideband Wireless Transceivers

   Author : Quoc-Tai Duong; Atila Alvandpour; Henrik Sjöland; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : The proliferation of portable communication devices combined with the relentless demand for higher data rates has spurred the development of wireless communication standards which can support wide signal bandwidths. Benefits of the complementary metal oxide semiconductor (CMOS) process such as high device speeds and low manufacturing cost have rendered it the technology of choice for implementing wideband wireless transceiver integrated circuits (ICs).

6. 4. Integrated Transceivers for Millimeter Wave and Cellular Communication

   Author : TOBIAS TIRED; Institutionen för elektro- och informationsteknik; []
   Keywords : receiver; LNA; mixer; bipolar; BiCMOS; SiGe; mm-wave; E-band; transmitter; PLL; PA; beam steering;

   Abstract : Abstract:This doctoral thesis is addresses two topics in integrated circuit design: multiband direct conversion cellular receivers for cellular frequencies and beam steering transmitters for millimeter wave communication for the cellular backhaul. The trend towards cellular terminals supporting ever more different frequency bands has resulted in complex radio frontends with a large number of RF inputs. READ MORE
