Title: | A new fractal-based design of stacked integrated transformers | Authors: | Stojanović, Goran Radovanović, Milan Radonić, Vasa |
Issue Date: | May-2008 | Journal: | Active and Passive Electronic Components | Abstract: | Silicon-based radio-frequency integrated circuits are becoming more and more competitive in wide-band frequency range. An essential component of these ICs is on-chip (integrated) transformer. It is widely used in mobile communications, microwave integrated circuits, low-noise amplifiers, active mixers, and baluns. This paper deals with the design, simulation, and analysis of novel fractal configurations of the primary and secondary coils of the integrated transformers. Integrated stacked transformers, which use fractal curves (Hilbert, Peano, and von Koch) to form the primary and secondary windings, are presented. In this way, the occupied area on the chip is lower and a number of lithographic processes are decreased. The performances of the proposed integrated transformers are investigated with electromagnetic simulations up to 20GHz. The influence of the order of fractal curves and the width of conductive lines on the inductance and quality factor is also described. | URI: | https://open.uns.ac.rs/handle/123456789/15500 | ISSN: | 0882-7516 | DOI: | 10.1155/2008/134805 |
