1. 1. Modeling and post-correction of pipeline analog-digital converters

   Författare :Samer Medawar; Peter Händel; Martin Gustafsson; KTH; []
   Nyckelord :;

   Sammanfattning : Integral nonlinearity (INL) for pipelined analog-digital converters (ADCs) operating at radio frequency is measured and characterized. A parametric model for the INL of pipelined ADCs is proposed and the corresponding least-squares problem is formulated and solved. LÄS MER

3. 2. Pipeline Analog-Digital Converters Dynamic Error Modeling for Calibration : Integral Nonlinearity Modeling, Pipeline ADC Calibration, Wireless Channel K-Factor Estimation

   Författare :Samer Medawar; Peter Händel; Niclas Björsell; Magnus Jansson; Dominique Dallet; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Analog-digital converter; integral nonlinearity; calbiration; K-factor estimation;

   Sammanfattning : This thesis deals with the characterization, modeling and calibration of pipeline analog-digital converters (ADC)s. The integral nonlinearity (INL) is characterized, modeled and the model is used to design a post-correction block in order to compensate the imperfections of the ADC. LÄS MER
