A Third-Harmonic-Enhanced Triple-Push DCO Utilizing Source-Combining Technique 150 150
Author(s): Qiyao Jiang, Zhuo Xu, Quan Pan, Pui-In Mak, Rui P. Martins, Jun Yin

Abstract:

This article presents a detailed investigation into optimizing the amplitude and phase of the transistor’s terminal voltages to generate a high 3rd-harmonic current in the millimeter-wave (mm-Wave) frequency. Based on the analysis, the digitally controlled source-combining triple-push (SCTP) oscillator is derived to significantly enhance the 3rd-harmonic current by introducing …

A 60-GHz Class- F2,3 Standing-Wave Oscillator Employing Triple-Line Resonator Achieving −189-dBc/Hz FoM in 65-nm CMOS 150 150
Author(s): Wei-Yu Lin, Nikhil Jain, Jun-Chau Chien

Abstract:

Implementing oscillators with harmonic engineering beyond 60-GHz poses significant challenges due to the need for small inductors resonating beyond 120 GHz. To address this issue, this work presents a 60-GHz standing-wave oscillator (SWO) with both second- and third-harmonic boosting for phase noise reduction. A triple-line resonator is proposed to sustain both …
