All-digital PLL and transmitter for mobile phones
Robert Bogdan Staszewski,John Wallberg,Sameh S. Rezeq,Chih-Ming Hung,Oren Eliezer,Sudheer Vemulapalli,C. Fernando,Kenneth J. Maggio,Robert B. Staszewski,N. Barton,Meng-Chang Lee,P. Cruise,Manouchehr Entezari,Khurram Muhammad,Dirk Leipold +14 more
TL;DR: The first all-digital PLL and polar transmitter for mobile phones is presented, exploiting the new paradigm of a deep-submicron CMOS process environment by leveraging on the fast switching times of MOS transistors, the fine lithography and the precise device matching, while avoiding problems related to the limited voltage headroom.
Journal ArticleDOI
All-digital TX frequency synthesizer and discrete-time receiver for Bluetooth radio in 130-nm CMOS
Robert Bogdan Staszewski,Khurram Muhammad,Dirk Leipold,Chih-Ming Hung,Yo-Chuol Ho,John Wallberg,C. Fernando,Ken Maggio,Roman Staszewski,T. Jung,Jinseok Koh,S. John,I. Deng,Vivek Sarda,O. Moreira-Tamayo,Valerian Mayega,Ran Katz,Ofer Friedman,Oren Eliezer,Elida de-Obaldia,Poras T. Balsara +20 more
TL;DR: In this paper, the authors present a single-chip fully compliant Bluetooth radio fabricated in a digital 130-nm CMOS process, which is compatible with digital deep-submicron CMOS processes and can be readily integrated with a digital baseband and application processor.
Journal ArticleDOI
Digitally controlled oscillator (DCO)-based architecture for RF frequency synthesis in a deep-submicrometer CMOS Process
TL;DR: The presented ideas enable the employment of fully-digital frequency synthesizers using sophisticated signal processing algorithms, realized in the most advanced deep-submicrometer digital CMOS processes which allow almost no analog extensions.
Proceedings ArticleDOI
All-digital PLL and GSM/EDGE transmitter in 90nm CMOS
Robert Bogdan Staszewski,John Wallberg,Sameh S. Rezeq,Chih-Ming Hung,Oren Eliezer,Sudheer Vemulapalli,C. Fernando,Kenneth J. Maggio,Robert B. Staszewski,N. Barton,Meng-Chang Lee,P. Cruise,Manouchehr Entezari,Khurram Muhammad,Dirk Leipold +14 more
TL;DR: A 1.2V 42mA all-digital PLL and polar transmitter for a single-chip GSM/EDGE transceiver is implemented in 90nm CMOS and achieves -165dBc/Hz phase noise at 20MHz offset, with 10 /spl mu/s settling time.
Proceedings ArticleDOI
