Small-Signal Modeling of pHEMTs and Analysis of their Microwave Performance [PDF]

Journal of Engineering and Applied Sciences, 2010
Accurate extraction of the small-signal equivalent circuit of GaAs microwave Field Effect Transistors (GaAs FET) is crucial for efficient design of microwave analog circuits such as Low Noise Amplifiers (LNAs). This study proposed an improved direct analytical extraction procedure. Its efficiency was demonstrated through the characterisation of two 1μm

Compact conversion and cyclostationary noise modelling of pn junction diodes in low-injection - Part I: Model derivation [PDF]

, 2004
Starting from the well known low-injection approximation, a closed form, analytical compact model is derived for the small-signal (SS) and forced quasi-periodic operation of junction diodes. The model determines the small-signal and conversion admittance

Quasi-Electromechanical Oscillation Analysis of VSG Grid-Connected System Based on Small-Signal Model

IEEE Access
VSG is a pivotal control strategy for GFM, designed to enhance the damping and inertia of power systems, thereby bolstering their stability. Despite its benefits, VSG can induce a QEO due to dynamic interactions between the GFM and the power system. This

Small-Signal Modeling of Mutual Saturation in Induction Machines [PDF]

IEEE Transactions on Industry Applications, 2010
A small-signal model is derived for saturated induction machines. Inductances are allowed to saturate as a function of their own current (or flux), and the mutual saturation effect originating mainly from skewed or closed rotor slots is also included in the model.

Infant Embryonal CNS Tumors: Molecular Insights and Treatment Considerations for Contemporary Pediatric Neuro‐Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Embryonal tumors comprise the majority of malignant central nervous system (CNS) neoplasms diagnosed in children under 3 years of age. Compared with their counterparts in older children, these tumors exhibit distinct molecular biology and a more aggressive clinical phenotype, while their management is complicated by the heightened ...

Accurate Small-Signal Modeling of FD-SOI MOSFETs [PDF]

IEICE Transactions on Electronics, 2006
A new small-signal model for fully depleted silicon-on-insulator (FD-SOI) MOSFETs operating at RF frequencies is presented. The model accounts for the non-quasi-static effect by determining model parameters using a curve fitting procedure to reproduce the frequency response of FD-SOI MOSFETs.

Safety and Effectiveness of a High‐Dose, Tailored Tissue Plasminogen Activator Therapy Protocol: A Joint Pediatric Hematology and Cardiac ICU Quality Improvement Initiative Analysis

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric thromboembolism is increasingly encountered in critical care. Systemic thrombolysis with tissue plasminogen activator (tPA) facilitates vessel or valve patency, yet pediatric‐specific protocols remain undefined, and safety concerns persist. Objective To evaluate the efficacy and safety of a tailored, prolonged systemic tPA
