Author(s): Yevhenii Mormul, Patchara Sawakewang, Sayan Kumar, Chawin Khongprasongiri, Teerachot Siriburanon, Robert Bogdan Staszewski

Abstract:

We introduce a new class-F3,5 oscillator topology that enables quadrature operation by duplicating a conventional class-F3 oscillator core and electro-magnetically coupling the two cores through a pair of additional coils feeding source terminals of the gm transistors. The coupling network enhances the 5th-harmonic component, enabling efficient extraction and quadrature operation …

A Third-Harmonic-Enhanced Triple-Push DCO Utilizing Source-Combining Technique

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 15-MHz, 2.7-mm2 Notch-Free Hybrid Magnetic Current Sensor With Feedforward Ripple Cancellation and ±0.8% Local Gain Non-Uniformity

A 15-MHz, 2.7-mm2 Notch-Free Hybrid Magnetic Current Sensor With Feedforward Ripple Cancellation and ±0.8% Local Gain Non-Uniformity 150 150
Author(s): Feng Cheng, Jianlin Xia, Encheng Zhu, Long Zhang, Zhongyuan Fang, Xiaofeng Sun, Dejin Wang, Shaoping Li, Jing Zhu, Yongjia Li, Weifeng Sun

Abstract:

This article proposes a hybrid magnetic current sensor achieving a 15-MHz bandwidth within a compact 2.7-mm2 area. To mitigate the pole–zero mismatch inherent in the two-stage integrator topology, a dual-output Gm-C integrator with subtractor-based compensation is proposed, achieving a ±0.8% local gain non-uniformity. A wideband feedforward ripple suppression scheme cancels …

An Inductive-Load-Modulated Multiband Phase Shifter With <0.38°/0.12-dB RMS Errors

An Inductive-Load-Modulated Multiband Phase Shifter With <0.38°/0.12-dB RMS Errors 150 150
Author(s): Xinyi Wu, Chenxu Zhao, Hui Chen, Xun Bao, Yaolong Hu, Aoyang Zhang, Leibo Liu

Abstract:

This letter presents a compact, multiband reflection-type phase shifter (RTPS) implemented in 65-nm CMOS that overcomes the narrowband limitations of conventional passive loads. The proposed design utilizes an inductive-load modulation. By injecting a secondary signal to actively manipulate the magnetic flux, the equivalent inductance is boosted to enable operation across …

FeFET-Based CMOS Current Starvation Programmable Delay Element

FeFET-Based CMOS Current Starvation Programmable Delay Element 150 150
Author(s): Albi Mema, Simon Thomann, Hussam Amrouch

Abstract:

Programmable delay elements (PDEs) are crucial circuit building blocks that enable precise timing adjustments of signal transitions. They are used in various critical applications, like time-to-digital converters. They are often used to mitigate aging by clock skew tuning postfabrication. However, typical CMOS PDE designs require many transistors while still offering …

P-Dits for the Frequency Assignment Problem With Transmitter Deactivation in Dense Environments

P-Dits for the Frequency Assignment Problem With Transmitter Deactivation in Dense Environments 150 150
Author(s): Christian Duffee, Jordan Athas, Igor Kadota, Randall Berry, Pedram Khalili Amiri

Abstract:

The frequency assignment problem is a nondeterministic polynomial-time hard (NP-hard) optimization problem concerning the assignment of frequency channels to wireless transmitters. Typically, the aim is to minimize interference between transmitters while maintaining a high level of service. In this work, the use of probabilistic d-dimensional bits, or p-dits, for this …
