    摘要: A system provides push services and information to mobile stations via broadcast messages. The broadcast messages are made on predetermined cell broadcast channels, which are associated with an inbox on the mobile stations. Contained within the messages are Uniform Resource Locators (URL) that, when accessed, provide multimedia and other rich content to the mobile station. The system allows wireless carriers to provide features such as Wireless Access Protocol (WAP) push operations via cell broadcast to many mobile stations in a geographic area without the need to individually address messages to the mobile stations.

    摘要: A programmable reference-less oscillator provides a wide range of programmable output frequencies. The programmable reference-less oscillator is implemented on an integrated circuit that includes a free running controllable oscillator circuit such as a voltage controlled oscillator (VCO), a programmable divider circuit coupled to divide an output of the controllable oscillator circuit according to a programmable divide value. A non-volatile storage stores the programmed divide value and a control word that controls the output of the controllable oscillator circuit. The control word provides a calibration capability to achieve a desired output frequency in conjunction with the programmable divider circuit. Open loop temperature compensation is achieved by adjusting the control word according to a temperature detected by a temperature sensor on the integrated circuit. Additional clock accuracy may be achieved by adjusting the control word for process as well as temperature.

    摘要: An oscillator circuit may be used with controller circuits that are designed to operate with crystals, with no modifications to the pinout or firmware of the controller circuit. In some embodiments, the oscillator circuit includes an enable input that is responsive to low-amplitude transitions, which may be coupled to and driven by the crystal output signal of the controller circuit. When transitions are present on the crystal output signal, the oscillator circuit enables its clock output signal. When the controller circuit disables its crystal output signal, the oscillator circuit no longer detects transitions on the crystal output signal coupled to the oscillator circuit enable input, and disables the clock output signal.

    摘要: Semiconductor devices can be fabricated using conventional designs and process but including specialized structures to reduce or eliminate detrimental effects caused by various forms of radiation. Such semiconductor devices can include the one or more parasitic isolation devices and/or buried guard ring structures disclosed in the present application. The introduction of design and/or process steps to accommodate these novel structures is compatible with conventional CMOS fabrication processes, and can therefore be accomplished at relatively low cost and with relative simplicity.

    摘要: A phase-locked loop (PLL) achieves initial lock using a course fractional-N divider driving a binary phase detector. Once frequency lock is achieved, this divider may be turned off, while an adaptive phase detector takes over control of the PLL front end. The adaptive phase detector (APD) receives input directly from the VCO and the reference clock, deriving digital control signals and a precision phase detector output. The APD operates at the update rate, generating a digital delta sigma modulator (DSM) data stream output at the update rate. The APD automatically locks to a digitally generated ramp corresponding to an expected difference between the VCO output and the reference clock, while adaptively correcting for DC errors and ramp cancellation errors.

    摘要: A reversible polarity decoder circuit is disclosed which is particularly suitable for implementing a multi-headed decoder structure, such as might be used for decoding word lines, and particularly in a 3D memory array. The decoder circuit provides an overdrive voltage bias to the gates of half-selected word line driver circuits to solidly maintain the half-selected word lines at an inactive level. If the memory array is biased at or near the breakdown voltage, this overdrive voltage may be greater than the breakdown voltage of the decoder transistors. However, in the embodiments described, the decoder circuit accomplishes this without impressing a voltage greater than the breakdown voltage across any of the decoder transistors, for either polarity of operation of the decoder circuit.
