    Sammanfattning : The analysis of general charge sampling technique is presented in this thesis. Charge sampling integrates input current instead of tracking input voltage to realize high speed and low voltage sampling. The analysis focuses on the performance of general charge sampling circuits for signal capture. LÄS MER

  5. 4. ADC modeling from a system perspective and design of RF-sampling radio receivers

    Författare :Kalle Folkesson; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : The analog-to-digital converter (ADC) is the key component in many modem electronic systems. Examples are wire-line communication systems such as digital subscriber line modems, wireless communication systems such as radio receivers, and sensor systems such as military radar. LÄS MER

  7. 5. Reconfigurable Receiver Front-Ends for Advanced Telecommunication Technologies

    Författare :Iman Ghotbi; Integrerade elektroniksystem; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 5G; Receiver; Filter; Low-noise amplifier; FD-SOI; Calibration;

    Sammanfattning : The exponential growth of converging technologies, including augmented reality, autonomous vehicles, machine-to-machine and machine-to-human interactions, biomedical and environmental sensory systems, and artificial intelligence, is driving the need for robust infrastructural systems capable of handling vast data volumes between end users and service providers. This demand has prompted a significant evolution in wireless communication, with 5G and subsequent generations requiring exponentially improved spectral and energy efficiency compared to their predecessors.
