  1. 1. Integrated Variable-Gain and CMOS Millimeter-Wave Amplifiers

    Author : Mohammad Anowar Masud; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LNA; MMIC; FinFET; CMOS; HEMT; GaAs; WLP; VGA; BCB;

    Abstract : Variable Gain Amplifier finds extensive use in the high frequency demonstrators specially those operating in the millimeter-wave regions and beyond where the incoming RF signal level can have wide variations. To maintain a constant signal level an IF VGA has been designed that can offer a dynamic variation of gain as much as 45 dB together with a high maximum gain and a low noise figure. READ MORE

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

    University dissertation from Stockholm : KTH

    Author : Saul Alejandro Rodriguez Duenas; KTH.; [2009]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; LNA; mixer; 4G; TECHNOLOGY Electrical engineering; electronics and photonics Electronics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik 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

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

    University dissertation from Department of Electrical and Information Technology, Lund University

    Author : Markus Törmänen; [2010]
    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. 4. Microwave CMOS LNAs and VCOs - Using Passives On-Chip, Above Chip, and Off-Chip

    University dissertation from Department of Electrical and Information Technology, Lund University

    Author : Lars Aspemyr; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VCO; LNA; CMOS; Wafer-Level-Packaging; Ferro-electric varactor; System-on-Package;

    Abstract : The performance of LNAs and VCOs is of large importance to the complete wireless communications system. To achieve sufficient performance in microwave applications, LNAs and VCOs have therefore up to now mostly been manufactured in advanced and expensive semiconductor technologies. READ MORE
