  • Publication number: 20140050287
    Abstract: A receiver for reducing a system start-up time includes an antenna, an RF (Radio Frequency) circuit, a demodulation circuit, and a data slicer. The data slicer includes a filter, a comparator, a switch, and a delay generator. The filter filters a demodulated signal so as to generate a threshold level. The comparator has a positive input terminal for receiving the demodulated signal and a negative input terminal for receiving the threshold level. The comparator compares the demodulated signal with the threshold level so as to generate a digital signal. The switch is coupled between the positive input terminal and the negative input terminal. The delay generator determines whether or not to close the switch during a delay time according to an enable signal.

  • Patent number: 7115513
    Abstract: A method for forming uniform, sharply defined periodic regions of reversed polarization within a unidirectionally polarized ferroelectric material proceeds as a two-step process. First, alignment keys are formed on upper and lower planar surfaces of a unidirectionally polarized ferroelectric material by producing a spaced pair of alignment key shaped domain reversed regions and etching alignment key shaped notches in the upper and lower surfaces where the domain reversed regions intersect the surface planes. These notches, being vertically aligned between the upper and lower surfaces, are then used to align photomasks over a surface coating of photoresist formed directly on the material surface or on SiO2 layers coating the material surface.

  • Patent number: 6900928
    Abstract: A method of patterning and fabricating poled dielectric microstructures in dielectric materials comprising the following steps. A poled dielectric microstructure within a dielectric material is provided. The poled dielectric microstructure is then segmented into a plurality of independent sub-structures. The poled dielectric microstructures are then fabricated within each of the plurality of independent sub-structures. Additional processes and a novel poling setup for improving and implementing this patterning and fabrication method are also disclosed.
