  • Low-voltage crystal oscillator circuit compatible with GPIO
    Patent number: 10523155
    Abstract: Low voltage crystal oscillator having native NMOS transistors used for coupling/decoupling to/from GPIO. The native NMOS transistors function properly at a low supply voltage when on (low resistance) and a high supply voltage when off (high resistance). Oscillator Gm driver bias resistors are repurposed to degenerate the native NMOS transistors when they are off, thereby reducing the leakage current thereof (oscillator circuit decoupled from GPIO nodes). This ensures compliance with the CMOS IIH leakage current specification during an external clock (EC) mode at a high supply voltage.

  • Method and computer program for collecting, rating, and making available electronic information
    Publication number: 20030217056
    Abstract: A method and computer program for collecting, rating, and making available information on the World Wide Web and other information sources. The method broadly comprises the steps of: collecting information relating to a particular subject; rating the information; gathering additional information relating to the rated information; indexing the rated information; identifying and applying desired client-user parameters to the rated information; identifying and applying desired end-user parameters to the rated information; and if the rated information meets the client-user and end-user parameters, displaying at least one item of information meeting the client-user and end-user parameters. The method may further includes the steps of: managing the client-user account; and generating usage statistics.
