    Sammanfattning : Technology scaling in advanced CMOS nodes has been very successful in reducing the cost and increasing the operating frequency, however, it has also resulted in reduced transistor intrinsic gain and increased thermal noise coefficient, and most importantly, deteriorated linearity performance. At the same time, advanced wireless communication standards offer ever increasing data rates and pose more stringent requirements on coexistence, leading to very stringent linearity requirements.

  3. 2. Digitally controlled analog multiply-accumulate units

    Författare :Mattias Duppils; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis is about digitally controlled analog multiplier-accumulator (MAC) units and their utilization in communications applications. These units are implemented as switched-capacitor circuits, designed with switches (MOS transistors), capacitors (MOS transistors), and amplifiers (MOS transistors); using a CMOS technology. LÄS MER
