Investigations about Al and Cu-Based Planar Spiral Inductors on Sapphire for GaN-Based RF Applications

Analysis, Design and Optimization of On-Chip Inductors on Sapphire for Gan based Rfics

The on chip spiral inductors are one of the key components in the development of the RFIC‟s as they determine the performance of the circuits such as VCO, LNA, mixers etc. In this paper, the design of an inductor for GaN based RFICs operating in C-band is presented. Sapphire (Al2O3), which is a common substrate for GaN, is used as substrate and silicon nitride (Si3N4), which is a common passiva...

On the Design of RF Spiral Inductors on Silicon

This review of design principles for implementation of a spiral inductor in a silicon integrated circuit fabrication process summarizes prior art in this field. In addition, a fast and physics-based inductor model is exploited to put the results contributed by many different groups in various technologies and achieved over the past eight years into perspective. Inductors are compared not only b...

در سالهای اخیر،اختلالات کیفیت توان مهمترین موضوع می باشد که محققان زیادی را برای پیدا کردن راه حلی برای حل آن علاقه مند ساخته است.امروزه کیفیت توان در سیستم قدرت برای مراکز صنعتی،تجاری وکاربردهای بیمارستانی مسئله مهمی می باشد.مشکل ولتاژمثل شرایط افت ولتاژواضافه جریان ناشی از اتصال کوتاه مدار یا وقوع خطا در سیستم بیشتر مورد توجه می باشد. برای مطالعه افت ولتاژ واضافه جریان،محققان زیادی کار کرده ...

Electrical Characteristics of Planar Spiral Inductors

This paper describes two types of PEEC-based methods for the analysis of planar spiral inductors. One approach is a high-level distributed network method (DNM), while the second is based on a relatively simple equivalent SPICE circuit. The inductors are printed on lossless, grounded ceramic substrates and the metallization is assumed to have finite conductivity, but is infinitesimally thin, so ...
