1. 6. System Analysis and Implementation of Delta-Sigma Modulator Topologies with Low Gain Amplifiers in 90nm CMOS

   Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Författare :Bilal Shahzad; [2011]
   Nyckelord :;

   Sammanfattning : Data converters are one of the key components in many applications ranging from wireless communication to data acquisitions system, sensors, audio electronics, video display electronics and analog microcontrollers. All of these use some type of data converter to perform the task of signal processing/condition for example in RF transceivers the received analog signal after passing through filters is converted to digital signal for further processing.

4. 8. Low-Power Low-Noise IQ Modulator Designs in 90nm CMOS for GSM/EDGE/WCDMA/LTE

   Uppsats för yrkesexamina på avancerad nivå, Institutionen för systemteknik

   Författare :Mattias Johansson; Jonas Ehrs; [2010]
   Nyckelord :RF; ASIC; Analog Integrated Circuit; IQ Modulator; IQM; CMOS; 90nm; Predistortion; Mixer; Envelope Tracking; Direct Conversion;

   Sammanfattning : The current consumption of the IQ modulator is a significant part of the totalcurrent consumption of a mobile transmitter platform and reducing it is of greatinterest. Also, as the WCDMA/LTE standards specifies full duplex transmissionsand Tx and Rx are most often using the same antenna, it is crucial to have asolution with low noise generation. LÄS MER

5. 9.  A Wideband High Dynamic Range Continuous-Time Sigma-Delta ADC for Wireless Applications

   Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Författare :Ye Xu; [2010]
   Nyckelord :;

   Sammanfattning : In recent years, the research toward the development of high speed and high resolution analog-to-digital converters (ADCs) has been equally driven by the demand of high-speed wire line and wireless communication services. Delta-Sigma ADCs are widely used in wireless applications due to their oversampling and noise shaping characteristics. LÄS MER
