Regulated cascode-based vertical filter

Electronics Letters, 2001
An approach to realise a low-power, high-order, very-high-frequency current-mode filter is proposed. The filter utilises vertical connection of regulated-cascode (RGC) biquads to reduce current consumption. Simulation results of a fourth-order Chebyshev lowpass filter are demonstrated.

AlGaN/GaN Dual‐Gate HEMT Using a High Al Mole Fraction and Thin Barrier Layer

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This article examines the use of a high Al mole fraction (x = 0.34) and a thin barrier layer (t = 11.5 nm) in AlGaN/GaN high electron mobility transistors (HEMTs) with both single‐gate and dual‐gate configurations. Single‐gate HEMTs with the current epitaxial structure demonstrated an improved maximum drain current and transconductance, as well as ...

A Framework for Online Estimation of High Frequency Converter Circuit Parameters

Electronics Letters, Volume 61, Issue 1, January/December 2025.
In this paper a parameter estimation method of high frequency switching power converters is proposed. Parameters are estimated through measurement of basic circuit voltage and current quantities and using simple feed forward neural networks to establish correlations between circuit parameter variations and general converter performance.
