2. 1. Multi-Band Multi-Standard CMOS Receiver Front-Ends for 4G Mobile Applications

   Author : Saul Alejandro Rodriguez Duenas; Ana Rusu; Mohammed Ismail El-Naggar; Erik Bruun; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; LNA; mixer; 4G; Electronics; Elektronik;

   Abstract : The development of the transistor and its continuous down-scaling has allowed during the last decades the appearance of cheap wireless communication systems targeting consumer products. The complexity of these systems has increased dramatically during the last years, mainly fueled by both the Moore law and improvements in communication theory. READ MORE

   Author : Carl Bryant; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; receiver; front-end; sensor networks; CMOS; ultra-low power; low noise amplifier; mixer; voltage-controlled oscillator; frequency divider; bluetooth;

   Abstract : Historically, research on radio communication has focused on improving range and data rate. In the last decade, however, there has been an increasing demand for low power and low cost radios that can provide connectivity with small devices around us. READ MORE

5. 3. Design Aspects of Fully Integrated Multiband Multistandard Front-End Receivers

   Author : Adiseno; KTH; []
   Keywords : low-noise amplifier; mixer; RF front-end; wireless receiver; noise figure; linearity; bandwidth; dual-loop feedback;

   Abstract : In this thesis, design aspects of fully integrated multibandmultistandard front-end receivers are investigated based onthree fundamental aspects: noise, linearity and operatingfrequency. System level studies were carried out to investigatethe effects of different modulation techniques, duplexing andmultiple access methods on the noise, linearity and selectivityperformance of the circuit.

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; D-band; frequency multiplier; 110-170 GHz; QPSK; demodulator; I Q modulator; transmitter; high-order modulation; receiver; high data rate; single chip; SiGe BiCMOS; QAM; InP DHBT; direct conversion; Gilbert-cell mixer; millimeter-wave communication; 5G; MMIC; point-to-point radio.;

   Abstract : Today’s main driving parameter for radio transceiver research is the ability to provide high capacity while maintaining low cost, small form factor, and low power consumption. Direct conversion architectures (due to the feasibility of monolithic integration) at millimeter-wave (due to wideband availability) have attracted large interest in recent years because of their potential to meet these demands.

7. 5. High Performance LNAs and Mixers for Direct Conversion Receivers in BiCMOS and CMOS Technologies

   Author : TOBIAS TIRED; Institutionen för elektro- och informationsteknik; []
   Keywords : LNA; mixer; direct conversion receiver;

   Abstract : The trend in cellular chipset design today is to incorporate support for a larger number of frequency bands for each new chipset generation. If the chipset also supports receiver diversity two low noise amplifiers (LNAs) are required for each frequency band. This is however associated with an increase of off-chip components, i.e. READ MORE
