    Sammanfattning : Sequential 3D (S3D) integration has been identified as a potential candidate for area efficient ICs. It entails the sequential processing of tiers of devices, one on top the other. LÄS MER

  2. 2. Low Noise Oscillator in ADPLL toward Direct-to-RF All-digital Polar Transmitter

    Författare :Jian Chen; Li-Rong Zheng; Fredrik Jonsson; Hannu Tenhunen; Georges Gielen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; all-digital; digitally-intensive; frequency modualtion; phase modulation; amplitude modulation; polar; transmitter; oscillator; digital controled oscillator; DCO; VCO; voltage controled oscillator; class-C oscillator; class-D PA; ADPLL; phase noise; RF; CMOS.;

    Sammanfattning : In recent years all-digital or digitally-intensive RF transmitters (TX) have attracted great attention in both literature and industry. The motivation is to implement RF circuits in a manner suiting advanced nanometer CMOS processes. To achieve that, information is encoded in the time-domain rather than voltage amplitude. LÄS MER

  3. 3. Reconfigurable Analog to Digital Converters for Low Power Wireless Applications

    Författare :E. Martin I. Gustafsson; Ana Rusu; Georges Gielen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Integrated Circuits; Analog to Digital Converters; Wireless communication; Electronics Engineering; Electrical Engineering; Electronics; Elektronik;

    Sammanfattning : The commercialization of Marconi’s radio transmission and reception, along with the development of integrated circuits in the 1960’s have facilitated many new consumer products for wireless communication, where the mobile phones or handsets are one. These handsets started out as a portable phone, mounted in cars, and have with time added additional services as Short Message Service, and have today become a media center with global positioning, and high-speed internet connection.

  4. 4. A computer-aided approach to design of robust analog circuits

    Författare :Emil Hjalmarson; Georges G.E. Gielen; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analog circuit design; computer-aided design; Electrical engineering; Elektroteknik;

    Sammanfattning : Traditional design methods for analog circuits are based on rules-of-thumbs, experience, and trial-and-error approaches involving the use of circuit simulators. It is an unstructured process, which is time-consuming, error prone, and requires the attention of a skilled analog designer. LÄS MER

  5. 5. An optimization-based approach to efficient design of analog circuits
