  2. 1. Power-Efficient Continuous-Time Incremental Sigma-Delta Analog-to-Digital Converters

    Author : Sha Tao; Ana Rusu; Franco Maloberti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; analog-to-digital conversion; sigma-delta modulation; incre- mental ADC; two-step ADC; continuous-time; biosensor applications.;

    Abstract : Over the past decade, there has been a growing interest in the devel- opment of integrated circuits (ICs) for wearable or implantable biosensors, aiming at providing personalized healthcare services and reducing the health-care expenses. In biosensor ICs, the analog-to-digital converter (ADC) is a key building block that acts as a bridge between analog signals and digital processors. READ MORE

  7. 5. Multi-Level Lossless Phase Modulation in Liquid Crystals for High-Speed Spatial Light Modulators

    Author : David Engström; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; phase measurements; polarization; phase modulation; beam steering; Spatial light modulators; diffractive optics; ferroelectric liquid crystals;

    Abstract : The spatial light modulator (SLM) is a compact device that enables highly precise control of light propagation with low drive voltages and no moving parts. By imposing a certain phase modulation onto the incident lightwave, functions such as multi-beam steering, beam shaping, and air turbulence corrections can be achieved in realtime. READ MORE
