    Wireless RF Front-End Design: from ULP to mmW
    June 18-22, 2018
    EPFL Premises, Lausanne, Switzerland

    System Overview (2 Modules)
    Antonio Liscidini, University of Toronto

    After a first introduction of the requirements of a wireless transceiver, the main characteristics of ultra-low power radio will be analyzed. The system overview will continue with the description of two of the most used standard for ultra-low power wireless communications: ZigBee and Bluetooth Low Energy. After that, a design methodology to define the main specs of the radio starting from the physical layer of these two standards will be presented. The system overview will end by analyzing the most common and promising architecture for ultra-low power receivers and transmitters.

    Circuit Techniques for Low-Power Wireless (6 Modules)
    Antonio Liscidini, University of Toronto

    The main building blocks of ultra-low power wireless transceiver will be discussed. Following the RX signal path, low noise amplifiers, mixer topologies and base band filters will be presented. Beside the most common approaches, particular solutions oriented to ultra-low power systems will be included such as, quadrature low noise amplifiers, self-oscillating mixer, complex/poly-phase filters. The course will continue presenting the different topology used for the power amplifier (one of the most power hungry element in the transmitter side) and will continue with the analysis of the frequency generation required to perform signal down/up conversion in the radio. Different oscillator topologies, and quadrature generation schemes will be presented. The discussion on circuits techniques will end with the analysis of the power scalability and bias sharing approaches that can be used to minimize the power consumption of the radio through a clever re-configurability and cross-interaction between the different building blocks previously discussed.

    Actives and Passives at mm-Wave Frequencies
    Patrick Reynaert, KU Leuven

    Fundamental properties of transistors and passives components at mm-wave frequencies will be discussed. A brief overview of 2-port networks is given, as well as layout optimization of MOS transistors for high-frequency operation, gain and stability. The implementation of passives such as RLC, transformers, baluns, transmission lines and slow-wave transmission lines in MOS backend metallization is discussed with various examples.

    Fractional-N PLLs for Frequency Synthesis
    Ian Galton, UC San Diego

    This lecture explains the extension of integer-N PLLs to fractional-N PLLs for both fine tuning resolution and in-loop VCO modulation. It presents an overview of modulus quantization noise shaping techniques, tradeoffs associated with quantization noise shaping order and PLL loop bandwidth, non-ideal effects of particular concern in fractional-N PLLs such as charge pump nonlinearities and data-dependent multi-modulus divider delays, techniques for increasing loop bandwidth, simulation techniques, and case studies of example circuits and applications.
