  1. 1. Studies on Selected Topics in Radio Frequency Digital-to-Analog Converters

    Author : Mohammad Reza Sadeghifar; Jacob Wikner; Adam Strak; Linköpings universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAC; Telecommunication; Semi-digital FIR filter; RF DAC; Sigma Delta Modulator; DDFS;

    Abstract : The network latency in fifth generation mobile technology (5G) will be around one millisecond which is much lower than in 4G technology. This significantly faster response time together with higher information capacity and ultra-reliable communication in 5G technology will pave the way for future innovations in a smart and connected society.

  3. 3. CMOS Data Converters for Closed-Loop mmWave Transmitters

    Author : Victor Åberg; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CMOS; SAR ADC; IQ-modulator; Data converter; mmWave; RF-DAC;

    Abstract : With the increased amount of data consumed in mobile communication systems, new solutions for the infrastructure are needed. Massive multiple input multiple output (MIMO) is seen as a key enabler for providing this increased capacity. With the use of a large number of transmitters, the cost of each transmitter must be low.
