Moore's law has served as a goal for the semiconductor industry for more than 50 years.
After decades of relentlessly racing forward, convincing new evidence now shows that the …

Direct all-digital frequency synthesizers are favored by modern nanoscale CMOS
technologies but suffer from strong frequency spurs and timing irregularities. To counter …

This paper presents a low-power digital DLL-based clock generator. Once the DLL is locked,
it operates in open-loop mode to reduce deterministic clock jitter and the power dissipation …

This paper describes a CMOS 32-tap delay-locked delay line, realized with a shunt-
capacitor circuit scheme, with an on-chip calibration circuit that allows the on-field reduction …

All-digital frequency synthesis architectures with phase and polar Σ-Δ modulation feedback
loops are introduced as a means to overcome the inherent spectral-quality limitations of …

This is a rigorous mathematical theory of the operation of the flying-adder (FA) frequency
synthesizer (also called direct digital period synthesizer). The paper consists of two parts …
