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 presents the design of an active filter implemented in a 65nm CMOS technology and based on super source follower.
The original filter was 5th order low-pass Chebyshev-type with a cut-off frequency of 160 MHz, but it was to be changed into Butterworth-type because of the results, here both designs are shown.
The architecture is fully differential and it is based on Sallen-Key biquad structures with super source follower as an active element and resistors and capacitors as passive elements.

The design process starts with a study of the super source follower and a comparison of this circuit with the normal source follower.
After that the work is divided into different stages in order to get an easy design flow, starting with ideal models including limited bandwidth and gain, and then simulations with transistor level active elements are performed.

Finally, some measurements are presented to analyze the noise and linearity performance of the filter.
