We present the first all-digital PLL and polar transmitter for mobile phones. They are part of a
single-chip GSM/EDGE transceiver SoC fabricated in a 90 nm digital CMOS process. The …

A new and innovative paradigm for RF frequency synthesis and wireless transmitter design
Learn the techniques for designing and implementing an all-digital RF frequency …

Sinusoidal oscillators and waveform generators have numerous applications in electronics,
instrumentation, measurement, communications, control systems, and signal processing …

We propose and demonstrate the first RF digitally controlled oscillator (DCO) for cellular
mobile phones. The DCO is part of a single-chip quad-band fully compliant GSM transceiver …

In this paper, we apply correlation theory methods to obtain a model for the near-carrier
oscillator power-spectral density (PSD). Based on the measurement-driven representation of …

In this tutorial brief, we introduce a unified wideband phase-noise theory framework of
frequency synthesis based on a multirate timestamp modeling with “two-variables”. We …

This article presents a millimeter-wave (mmW) frequency synthesizer based on a new
charge-sharing locking (CSL) technique. A charge-preset capacitor is introduced for charge …

Precision oscillators are ubiquitous in modern electronic systems, and their accuracy often
limits the performance of such systems. Hence, a deep understanding of how oscillator …

The past several years have successfully brought all-digital techniques to the RF frequency
synthesis, which could arguably be considered one of the last strong bastions of the …

A 0.3–1.4 GHz all-digital phase locked loop (ADPLL) with an adaptive loop gain controller
(ALGC), a 1/8-resolution fractional divider and a frequency search block is presented. The …
