Design and Analysis of Windmill-Shaping-Geometry Eight-Phase Oscillator Incorporating Magnetic and Dual-Injection Coupling Techniques

Design and Analysis of Windmill-Shaping-Geometry Eight-Phase Oscillator Incorporating Magnetic and Dual-Injection Coupling Techniques 150 150
Author(s): Ya Zhao, Runchen Wang, Lingao Huang, Haitao Ren, Jun Yin, Pui-In Mak, Li Geng, Chao Fan

Abstract:

This article reports a compact millimeter-wave (mm-wave) quad-core eight-phase oscillator featuring magnetic coupling and dual-injection coupling. Specifically, the quad-core oscillator is integrated in an LC-ring configuration via a windmill-shaping transformer for phase noise (PN) and chip area reduction. The eight-phase oscillator could eliminate the oscillation mode ambiguity and save the …

A Pseudo-Series Resonance CMOS Oscillator

A Pseudo-Series Resonance CMOS Oscillator 150 150
Author(s): Jiawen Chen, Kai Xu, Teerachot Siriburanon, Robert Bogdan Staszewski

Abstract:

This article presents a single-core, low-phase-noise (PN) digitally controlled oscillator (DCO) employing a pseudo-series resonance (pseudo-SR) technique with a transformer-based resonator. The proposed pseudo-SR resonator offers two key advantages: 1) a low impedance with a 180° phase shift at the impedance pole, emulating series resonance (SR) to enable single-stage oscillation and reduce …

A Multi-Core Series-Resonance CMOS Oscillator

A Multi-Core Series-Resonance CMOS Oscillator 150 150
Author(s): Shiwei Zhang, Wei Deng, Haikun Jia, Zhihua Wang, Baoyong Chi

Abstract:

Multi-core and series-resonance (SR) techniques have been proposed to achieve ultra-low phase noise (PN) performance. In this article, a scalable ring-coupling scheme is proposed for multi-core expansion. The mechanism provides intrinsic oscillation and PN reduction without compromising the passive network, specifically tailored for the SR oscillator. The dual closed ring …
