Chaos in Si MMIC Oscillators [PDF]

open access: yes29th European Microwave Conference, 1999, 1999
This paper analyzes the dynamics of two Si circuits in miliimetric band for which chaotic responses had been experimentally observed. The aim has been to determine, in each case, the particular phenomena leading to the chaotic response, in order to avoid this behavior in future realizations of these circuits.

Effectiveness and safety of cenobamate after conversion to monotherapy or dual therapy in real‐world clinical practice

open access: yesEpileptic Disorders, Volume 28, Issue 3, Page 775-785, June 2026.
Abstract Objective Patients with drug‐resistant epilepsy (DRE) typically take multiple anti‐seizure medications (ASMs) and are at risk of treatment‐related adverse events (AEs). This study assessed the impact of cenobamate monotherapy or dual therapy in patients with drug‐resistant epilepsy.

Convective Organization in African Easterly Waves Observed During the NAMMA and CPEX‐CV Field Campaigns

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 6, 28 March 2026.
Abstract Fundamental questions remain about where and when convection will occur within African easterly waves. In this study, we aim to better understand the dynamical processes that govern moist convective organization at the meso‐alpha scale in tropical easterly waves using NASA airborne field campaigns and satellite observations.

A 2.5 mW D‐Band Broadband Simultaneous Noise‐ and Input‐Matched InP LNA

open access: yesElectronics Letters, Volume 62, Issue 1, January/December 2026.
This work presents a D‐band, ultra‐low‐power, broadband two‐stage low‐noise amplifier (LNA) implemented in a 250‐nm InP DHBT process. Using a simultaneous noise and input matching technique with a gain‐boosted feedback network, the LNA achieves 6.2 dB noise figure and 27 dB gain from 130 to 155 GHz while consuming only 2.5 mW.

A 24‐28 GHz GaAs Reflection‐Type Phase Shifter MMIC for 5G Mm‐Wave Application

open access: yesElectronics Letters, Volume 62, Issue 1, January/December 2026.
Reflective‐Type Phase Shifters (RTPS) can be implemented in GaAs technology operating at 24‐28 GHz. By incorporating an enhanced multi‐resonant structure with Schottky diodes, a relative phase shift of up to 180° is achieved. ABSTRACT This letter presents a millimetre‐wave continuously tunable reflection‐type phase shifter (RTPS) using a 0.25 µm GaAs ...
