    Abstract: A clock and data recovery circuit that does not use a reference clock and a method of recovering cocks and data, in which the clock and data recovery circuit includes a clock generation unit, a mirror delay unit, a preamble phase detection unit, and a sampling unit. The clock generation unit generates a clock signal such that a phase of the clock signal is locked to a phase of a data signal inputted to the clock generation unit. The mirror delay unit outputs a plurality of delayed preamble signals based on the preamble signal during a preamble period. The preamble phase detection unit provides the charge pump with a preamble phase detection signal having information on a phase difference between the preamble signal and the clock signal during the preamble period. The sampling unit extracts data from the data signal by sampling the data signal with the clock signal.

  • Publication number: 20070195488
    Abstract: An active material of the present invention has fine pores formed in the interlayer of a carbon material capable of exhibiting electrochemical double layer capacitance. The fine pores are formed by forming an oxidized graphite structure combined with oxygen in the interlayer of a part or whole of the carbon material containing soft carbon and then removing a part or whole of oxygen in the interlayer. A method for producing an energy storage active material for use in an electrochemical double layer capacitor comprises pre-treating a carbon material through heat treatment and oxidizing the pre-treated carbon material using an oxidant. The method further comprises reducing the oxidized carbon material through heat treatment. The interlayer distances of an active material for respective steps, measured by a powder X-ray diffraction method, are 0.33˜0.36 nm in the pre-treatment step, 0.5˜2.1 nm in the oxidation step, and 0.34˜0.5 nm in the reduction step.
