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 …

1–1.7-GHz Single-Voltage-Controlled Tunable MMIC BPF With Over 45-dB Rejection to 30 GHz Using Tapped Inductor Technique

1–1.7-GHz Single-Voltage-Controlled Tunable MMIC BPF With Over 45-dB Rejection to 30 GHz Using Tapped Inductor Technique 150 150
Author(s): Di Lu, Menghan Sun, Baoqi Zhu, Xin Jiang, Ming Yu

Abstract:

This article presents a novel fourth-order single-voltage-controlled (SVC) tunable monolithic microwave integrated circuit (MMIC) bandpass filter (BPF) for tunable filter bank applications. Utilizing the tapped inductor technique (TIT), the proposed filter achieves compact magnetic coupling with reduced loss, avoiding the use of bulky inductor- or transformer-based coupling structures. The filter …
