Instructions

Reading digital theses in the closed network of the Aalto University Harald Herlin Learning Centre

In the closed network of Learning Centre you can read digital and digitized theses not available in the open network.

The Learning Centre contact details and opening hours: https://learningcentre.aalto.fi/en/harald-herlin-learning-centre/

You can read theses on the Learning Centre customer computers, which are available on all floors.

Logging on to the customer computers

  • Aalto University staff members log on to the customer computer using the Aalto username and password.
  • Other customers log on using a shared username and password.

Opening a thesis

  • On the desktop of the customer computers, you will find an icon titled:

    Aalto Thesis Database

  • Click on the icon to search for and open the thesis you are looking for from Aaltodoc database. You can find the thesis file by clicking the link on the OEV or OEVS field.

Reading the thesis

  • You can either print the thesis or read it on the customer computer screen.
  • You cannot save the thesis file on a flash drive or email it.
  • You cannot copy text or images from the file.
  • You cannot edit the file.

Printing the thesis

  • You can print the thesis for your personal study or research use.
  • Aalto University students and staff members may print black-and-white prints on the PrintingPoint devices when using the computer with personal Aalto username and password. Color printing is possible using the printer u90203-psc3, which is located near the customer service. Color printing is subject to a charge to Aalto University students and staff members.
  • Other customers can use the printer u90203-psc3. All printing is subject to a charge to non-University members.

Abstract (eng):This thesis explores the suitability of silicon-on-insulator (SOl) CMOS technology for low-power RF IC design. Modeling aspects are considered from the designer’s point of view and a comparison between SOl CMOS and bulk CMOS technologies is done in both theoretical and practical levels.

A 2 GHz low noise amplifier (LNA) is presented as a study case and silicon-on-sapphire (SOS) technology is used as a SOl reference. The studies showed the benefits of SOS. Lower power consumption is attained by the use lower operation voltage, easier HF model compared to the bulk CMOS case, no back-gate-bias effect, no substrate coupling, more accurate inductor models and higher Q-values. Also the floating body effect (FBE) is negligible in the UTSi FD SOS process used in this study. The thing that support the use of the bulk CMOS process is the easier availability of the bulk wafers which makes the bulk CMOS process less expensive.
Abstract (fin):Työssä tutkitaan SOl CMOS -teknologian sopivuutta pienitehoisten, radiotaajuisten integroitujen piirien toteuttamiseen. Työssä perehdytään MOSFETien mallintamiseen ja verrataan SOl CMOS -teknologiaa perinteiseen bulk CMOS -teknologiaan sekä teorian että käytännön tasolla.

Suunnitteluesimerkkinä toteutetaan 2 GHz:n LNA-piiri, ja SOl-teknologiareferenssinä käytetään sefiiripohjaista SOS-teknologiaa. Työssä tulee esille SOS-teknologian edut. Pienempi tehonkulutus saavutetaan pienemmillä käyttöjännitteillä, SOS:n yksinkertaisempi HF-malli, ei back-gate-bias efektiä, ei substraattikytkeytymistä, tarkemmat kelamallit ja korkeammat Q-arvot. FBE-efekti on mitätön työssä käytetyn UTSi FD SOS -teknologian tapauksessa. Bulk CMOS -teknologian käyttöä tukee kiekkojen helpompi saatavuus, mikä tekee bulk-teknologiasta edullisemman.
