  • Publication number: 20240162914
    Abstract: A modulo-based ADC implementation is provided and involves converting an input analog signal into phases of other M periodic analog reference signals based on one or more transfer functions, wherein M?2. The phase of each of the M reference signals comprises a folded signal corresponding to the input analog signal that is amplitude-folded to fall within a required amplitude range. This signal-to-phase conversion allows a modulo operation to be implemented over the input analog signal. Further, the M reference signals are used to obtain M discrete-time digital signals which, in turn, are used to obtain a digital representation of the input analog signal.

  • Patent number: 11929385
    Abstract: A method for forming a pixelated optoelectronic stack comprises forming a stacked layer structure that comprises a bottom electrode layer, an optoelectronic layer over the bottom electrode layer, and a patterned hard-mask comprising a pattern over the optoelectronic layer. The method comprises replicating the pattern into the optoelectronic layer and the bottom electrode layer, thereby forming a first intermediate pixelated stack comprising at least two islands of stack separated from one another by stack-free areas; providing an electrically insulating layer on the first intermediate pixelated stack; removing a top portion of the electrically insulating layer and removing any remaining hard-mask so that a top surface of the electrically insulating layer is coplanar with an exposed top surface of the first intermediate pixelated stack, yielding a second intermediate pixelated stack; and forming a top transparent electrode layer over the second intermediate pixelated stack.

  • Patent number: 8851270
    Abstract: A feeding unit for feeding media of varying thickness includes a plurality of rolling members defining a media feeding port therebetween, at least one pressing arm located on one of the rolling members, at least one elastic member, and a switch member. The pressing arm has a main body, a first pressing end formed on one end of the main body and a second pressing end formed on the other end of the main body, and the main body has a fulcrum thereon. The first pressing end is selectively connected onto said one of the rolling members. One end of the elastic member abuts against the first pressing end. The switch member is slidable to selectively press the second pressing end.
