Session B3: Wireless Technologies

Start Time: 13:30, Thursday, May 10
Room: Mt. Currie South
Chaired by Mohammad-Reza Nezhad-Ahmadi, University of Waterloo (mrnezhad@uwaterloo.ca)

  • 13:30 Andreia Cathelin, ST Microelectronics (andreia.cathelin@st.com)

    Analog RF mmw design in FD-SOI and new features enabled by body biasing techniques

  • 13:50 Shuhei Amakawa, Hiroshima University (amakawa@hiroshima-u.ac.jp)

    Feedback network design for transistor operating near its performance limit

    The growing demand for faster wireless communications is pushing radio frequencies in use higher up. Miniaturization of MOS transistors is still ongoing but their high-frequency performance has started to fall. Need is expected to arise to operate transistors near their performance limit. This talk will give an overview of recent progress in boosting transistor performance by circuit techniques, namely feedback. A design theory developed recently allows the designer to formulate equations for quickly finding a good initial design.

  • 14:10 Arun Natarajan, Oregon State University (nataraja@eecs.oregonstate.edu)

    Reconfigurable code/frequency/spatial filtering for full-duplex and frequency-domain duplex MIMO arrays

  • 14:30 Tanbir Haque, InterDigital (tanbir.haque@interdigital.com)

    Developing flexible architectures for wideband data reception and rapid interference detection for cognitive radio type applications

    A reconfigurable RF frontend (RFFE) architecture for signal reception and compressed-sampling (CS) wideband signal detection is presented. A cognitive radio (CR) dynamic shared spectrum access usecase where CR terminals rapidly gain awareness of their environments and opportunistically access unused blocks in the frequency-time resource space is used to motivate the proposed RFFE architecture. Evolution of the CS RFFE for sparse multi-band signal detection is presented. The Modulated Wideband Converter is briefly reviewed. The Quadrature Analog-to-Information Converter (QAIC) is then introduced and an approach for frequency domain analysis of the QAIC RFFE with linear impairments is developed. Building upon the direct-conversion RF chain, typically preferred for signal reception, and combining it with a flexible LO modulator and CS signal processing, the Direct RF-to-Information Converter (DRF2IC) unifying high- sensitivity signal reception, swept narrowband detection and CS wideband detection into a compact reconfigurable architecture is then introduced. Key frontend circuit blocks of the DRF2IC implemented on 65nm CMOS are described. Measurement results demonstrating the energy, speed and flexibility advantages of the proposed DRF2IC architecture is presented and benefits of the DRF2IC are contrasted with exiting conventional and other CS detection approaches.

  • 14:50 COFFEE BREAK (Mt. Curie Foyer, Sutcliffe Foyer)

  • 15:30 Rouzbeh Kananizadeh, University of California, Davis (rkanani@ucdavis.edu)

    Harmonic boosting in solid state circuits using harmonic positive feedback

    In my talk I will introduce a new concept for harmonic boosting based on linear time invariant behavior of nonlinear devices. Based on a new perspective on nonlinear electronics, I will expain how different harmonics translate to each other. By trapping the translations in a loop, second harmonic power is boosted dramatically in an oscillator, yielding high second harmonic output power and state-of-the-art phase noise performance at high millimeter wave frequencies.

  • 15:50 Christian Schlegel, Dalhousie University (Christian.Schlegel@Dal.ca) with K. El-Sankary and T. Sandhu

    Ultra-low power acoustic receiver with wake-mode

  • 16:10 Antonio Liscidini, University of Toronto (antonio.liscidini@utoronto.ca)

    Complex poles with passive switched capacitor filters
