On the Design of a High-Performance mm-Wave VCO With Switchable Triple-Coupled Transformer

TL;DR: In this article, a triple-coupled transformer is proposed to achieve a wide tuning range (TR) voltage-controlled oscillator (VCO) with a minimal adverse effect on the phase noise (PN).
Journal ArticleDOI

A 53–67 GHz Low-Noise Mixer-First Receiver Front-End in 65-nm CMOS

TL;DR: A mixer-first receiver front-end suitable for millimeter wave (mm-wave) applications is presented, including a modified single-balanced mixer core with an on-chip balun in order to provide a differential output from an injected single-ended local oscillator signal.
Journal ArticleDOI

A Wide-Tuning-Range Low-Phase-Noise mm-Wave CMOS VCO With Switchable Transformer-Based Tank

TL;DR: In this paper, a switchable transformer-based LC-tank is proposed to improve the frequency tuning range (TR) and low phase noise (PN) of a millimeter-wave complementary metaloxide semiconductor (CMOS) voltage-controlled oscillator.
Proceedings ArticleDOI

An 82.2-to-89.3 GHz CMOS VCO with DC-to-RF Efficiency of 14.8%

TL;DR: In this article, a 90 GHz CMOS voltage-controlled oscillator with a swing independent bias condition for the transistors at the frequency of interest is presented. But the trade-offs among efficiency and tuning range are also considered and the VCO achieves a peak DC-to-RF efficiency of 14.8% at 89.3 GHz and a wide tuning range of more than 8.3% while consuming only 8.5 mW of dc power from a 1.2-V supply.
Journal ArticleDOI

A 91-GHz Fundamental VCO With 6.1% DC-to-RF Efficiency and 4.5 dBm Output Power in 0.13- $\mu$ m CMOS

TL;DR: In this article, the authors present a systematic method for designing high-efficiency, high-power millimeter wave oscillators, which effectively manipulates the dc current of the drain of the core transistors to minimize the time during which the transistor is on Furthermore, an additional capacitor at the source of the transistor assists lowering the power consumption while maintaining the same fundamental generated power.
