摘要： Ultra-Wideband (UWB) technology exploits modulated coded impulses over a wide frequency spectrum with very low power over a short distance for digital data transmission. Today's leading edge modulated sinusoidal wave wireless communication standards and systems achieve power efficiencies of 50 nJ/bit employing narrowband signaling schemes and traditional RF transceiver architectures. However, such designs severely limit the achievable energy efficiency, especially at lower data rates such as below 1 Mbps. Further, it is important that peak power consumption is supportable by common battery or energy harvesting technologies and long term power consumption neither leads to limited battery lifetimes or an inability for alternate energy sources to sustain them. Accordingly, it would be beneficial for next generation applications to exploit inventive transceiver structures and communication schemes in order to achieve the sub nJ per bit energy efficiencies required by next generation applications.

摘要： Within many applications impulse radio based ultra-wideband (IR-UWB) transmission offers significant benefits for very short range high data rate communications when compared with existing standards and protocols. In many of these applications the main design goals are very low power consumption and very low complexity design for easy integration and cost reduction. Digitally programmable IR-UWB transmitters using an on-off keying modulation scheme on a 0.13 microns CMOS process operating on 1.2V supply and yielding power consumption as low as 0.9 mW at a 10 Mbps data rate with dynamic power control are enabled. The IR-UWB transmitters support new frequency hopping techniques providing more efficient spectrum usage and dynamic allocation of the spectrum when transmitting in highly congested frequency bands. Biphasic scrambling is also introduced for spectral line reduction. Additionally, an energy detection receiver for IR-UWB is presented to similarly meet these design goals whilst being adaptable to address IR-UWB transmitter specificity.

摘要： Optical spectroscopy is a widely used method to identify the chemical composition of materials and the characteristics of optical signals. Silicon based integrated photonics offers a platform for many optical functions through microelectromechanical systems (MEMS) and microoptoelectromechanical systems (MOEMS), silicon waveguides, integrated CMOS electronics and hybrid integration of compound semiconductor elements for optical gain. Accordingly, it would be beneficial to provide advanced optical tools for techniques such as optical spectroscopy and optical tomography exploiting MOEMS to provide swept filters that offer improved performance, increased integration, reduced footprint, reduced power consumption, increased flexibility, reconfigurability, and lower cost. Further, such MOEMS elements can support the provisioning of swept optical sources, swept filters, swept receivers etc. in the planar waveguide domain without free space optics.
