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.

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.
Journal ArticleDOI
A digitally controlled oscillator in a 90 nm digital CMOS process for mobile phones
TL;DR: This work proposes and demonstrates the first RF digitally controlled oscillator (DCO) for cellular mobile phones and analyzes the effect of the /spl Sigma//spl Delta/ dithering on the phase noise and shows that it can be made sufficiently small.
Journal ArticleDOI
The First Fully Integrated Quad-Band GSM/GPRS Receiver in a 90-nm Digital CMOS Process

TL;DR: The receiver in the first single-chip GSM/GPRS transceiver that incorporates full integration of quad-band receiver, transmitter, memory, power management, dedicated ARM processor and RF built-in self test in a 90-nm digital CMOS process is presented.
Journal ArticleDOI
A digitally controlled oscillator system for SAW-less transmitters in cellular handsets
TL;DR: The measured phase noise of -167 dBc/Hz at 20 MHz offset from 915 MHz carrier and frequency tuning range of 24.5% proves that this DCO system can be used in SAW-less quad-band transmitters for mobile phones.
