چکیده
Heterostructure field effect transistors (HFETs) are based on AlGaN/GaN heterostructures which offer excellent electronic properties for the development of faster, heat-resistant , energy efficient transistors and application in microwave-power amplifiers [1,2]. The outstanding device performance in cut-off frequency, breakdown voltage, and device output power [3,4]. However, the comparatively analysis of small signal and large signal parameters which are seldom found in this paper.

Design and Fabrication of a 911 GHz Balanced Low Noise Amplifier Using HJFET
This paper describes the design of an X-band balanced low noise amplifier (LNA) using an available HJFET device. The balanced LNA consists of a pair of electrically similar transistors whose input and output signals are divided or combined by 3 dB two-stage Wilkinson power dividers. The proposed balanced LNA is fabricated and measured. The measured results show that the noise figure is 1.30 dB ...
متن کاملAnalysis and study of geometrical variability on the performance of junctionless tunneling field effect transistors: Advantage or deficiency?
This study investigates geometrical variability on the sensitivity of the junctionless tunneling field effect transistor (JLTFET) and Heterostructure JLTFET (HJLTFET) performance. We consider the transistor gate dielectric thickness as one of the main variation sources. The impacts of variations on the analog and digital performance of the devices are calculated by using computer aided design (...

It has been recently shown that manufacturing p-n-junctions, field-effect and bipolar transistors, thyristors in a multilayer structure by diffusion or ion implantation with the optimization of dopant and/or radiation defects leads to increase the sharpness of p-n-junctions (both single p-n-junctions and p-n-junctions framework their system). Due to the optimization, one can also obtain increas...
