  • Publication number: 20160182023
    Abstract: Embodiments include apparatuses, methods, and systems for a circuit to shift a voltage level. The circuit may include a first inverter that includes a first transistor coupled to pass a low voltage signal and a second inverter coupled to receive the low voltage signal. The circuit may further include a second transistor coupled to receive the low voltage signal from the second inverter to serve as a feedback device and produce a high voltage signal. In embodiments, the first transistor conducts asymmetrically to prevent crossover of the high voltage signal into the low voltage domain. A low voltage memory array is also described. In embodiments, the circuit to shift a voltage level may assist communication between a logic component including the low voltage memory array of a low voltage domain and a logic component of a high voltage domain. Additional embodiments may also be described.

  • Publication number: 20150349894
    Abstract: A method and device for optical data transmission are disclosed. Data bits are transmitted in the form of data symbols, by modulating an optical signal in dependence on the data bits and in accordance with two or more constellation schemes. The data bits are transmitted, by generating first data symbols, which represent respective sets of data bits containing an even number of data bits. The first data symbols are generated, by modulating the optical signal in accordance with a first constellation scheme. Furthermore, the data bits are transmitted, by generating second data symbols, which represent respective sets of data bits having an odd number of data bits. The second data symbols are generated, by modulating the optical signal in accordance with a second constellation scheme. The first and the second data symbols are generated at a predefined symbol rate, such that the first and the second data symbols are interleaved in time.

  • Publication number: 20140264253
    Abstract: A nanowire device of the present description may include a highly doped underlayer formed between at least one nanowire transistor and the microelectronic substrate on which the nanowire transistors are formed, wherein the highly doped underlayer may reduce or substantially eliminate leakage and high gate capacitance which can occur at a bottom portion of a gate structure of the nanowire transistors. As the formation of the highly doped underlayer may result in gate inducted drain leakage at an interface between source structures and drain structures of the nanowire transistors, a thin layer of undoped or low doped material may be formed between the highly doped underlayer and the nanowire transistors.
