Journal ArticleDOI
State-of-the-Art and Future Directions of High-Performance All-Digital Frequency Synthesis in Nanometer CMOS
TL;DR: This paper revisits the digitization journey of the traditional charge-pump PLL that has resulted in an all-digital frequency synthesizer with the best-in-class RF performance while occupying only a fraction of the silicon area and consuming only a fractions of the power.
Journal ArticleDOI
A Fully Integrated Bluetooth Low-Energy Transmitter in 28 nm CMOS With 36% System Efficiency at 3 dBm

TL;DR: A new transmitter architecture for ultra-low power radios in which the most energy-hungry RF circuits operate at a supply just above a threshold voltage of CMOS transistors, and an all-digital PLL employs a digitally controlled oscillator with switching current sources to reduce supply voltage and power without sacrificing its startup margin.
Journal ArticleDOI
High-Resolution Millimeter-Wave Digitally Controlled Oscillators With Reconfigurable Passive Resonators
TL;DR: Two new millimeter-wave digitally controlled oscillators (DCOs) that achieve a tuning range >10% and fine frequency resolution 1 MHz simultaneously are described and two fine-resolution inductor-based and transformer-coupled DCOs are demonstrated in 90-nm CMOS.
Patent
Predistortion calibration and built in self testing of a radio frequency power amplifier using subharmonic mixing
TL;DR: In this article, a digital predistortion and built-in self-testing (BIST) scheme was proposed for a nonlinear digital-controlled radio frequency (RF) power amplifier (DPA) using subharmonic mixing.
Proceedings ArticleDOI
TDC-based frequency synthesizer for wireless applications
TL;DR: In this article, an all-digital PLL that is used in a commercial 130 nm CMOS single-chip Bluetooth radio is analyzed and further discussed details of the phase noise performance and performance.
