2. 1. Microwave CMOS VCOs and Front-Ends - using integrated passives on-chip and on-carrier

   Author : Markus Törmänen; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VCO; mixer; microwave; LNA; CMOS; front-end; System-on-Package;

   Abstract : The increasing demand for high data rates in wireless communication systems is increasing the requirements on the transceiver front-ends, as they are pushed to utilize more and wider bands at higher frequencies. The work in this thesis is focused on receiver front-ends composed of Low Noise Amplifiers (LNAs), Mixers, and Voltage Controlled Oscillators (VCOs) operating at microwave frequencies. READ MORE

4. 2. 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
