  • Patent number: 9350379
    Abstract: Apparatus and methods are taught for dividing a signal to be processed by a Noise Shaping (Hereafter NS) loop into smaller sections, and applying NS to at least a subset of these smaller sections. The processed signals are then recombined. As noise shaping is performed on smaller sections, the operating speed of each noise shaping loop, and accordingly for the system in general, is faster than if the output signal had been generated by single higher bit NS loop. Embodiments further include a configuration block for configuring the apparatus. For example, the number of sections, the section calculation method, and the NS for each section can each be configurable, and for some embodiments, programmable.

  • Publication number: 20160084780
    Abstract: A liquid concentration detecting device including a first substrate, a first temperature sensing element and a concentration sensor is provided. The first temperature sensing element and the concentration sensor are respectively disposed on opposite first surface and second surface of the first substrate. The concentration sensor includes a second substrate, a porous element, a heating element and a second temperature sensing element. The second substrate is disposed above the second surface. A portion of the liquid flows into the concentration sensor through the porous element, and the heating element heats the liquid in the concentration sensor. The second temperature sensing element measures the temperature variation of the liquid in the concentration sensor. The measured temperature and the temperature variation are compared to deduce a concentration of the liquid under detection.
