Abstract: A method for determining the carrier frequency offset and the corresponding sample-to- sample phase shift present in the sampled digital signal from the radio of a wireless transceiver is specified. The method divides the CFO range to be covered into a number of intervals and creates, from the received signal, as many parallel derived streams as there are interval endpoints, pre -compensating ("back rotating") the input by the sample-to-sample phase shift corresponding to the particular endpoint. It computes the magnitude and phase values of the correlation of a preamble pattern period with the preamble segment of each derived stream in parallel and uses the largest resulting magnitude value(s) to zoom in on the actual CFO present in the input stream. In order to improve accuracy in the presence of noise and provided there is still input preamble left to work on, it repeats the search for a shorter interval centered on the CFO value located in the first run. The finally located CFO value and the phase value from the corresponding correlation computation then determine the actual CFO and the corresponding sample-to-sample phase shift to be applied for pre- compensation ("back rotation") in an open-loop AFC.

Abstract: A power element bypass and voltage regulation circuit shutdown is used in a low drop out (LDO) bypass voltage regulator to minimize current drawn by the voltage regulator circuit when the supply input voltage approaches the regulated output voltage of the voltage regulation circuit. Two modes of operation are used in the low drop out (LDO) bypass voltage regulator. A regulate mode is used when the supply input voltage is greater than the reference voltage input, and a track mode is used when the supply input voltage is less than or equal to approximately the regulated output voltage of the voltage regulation circuit. Hysteresis may be introduced when switching between the regulate and track modes of operation.

Abstract: A mixed signal integrated circuit device, e.g., digital-to-analog converter (DAC), has a serial interface communication protocol that accesses volatile and/or non-volatile memory and allows a preprogrammed output voltage whenever the mixed signal device is powered- up. However, unlike conventional DACs, DACs with non- volatile memory may need special interface communication protocols for effective operation of the DAC and communications between a system master controller unit (MCU). Interface communications protocols that do not violate standard serial bus communications protocols are provided for communicating between the volatile and non- volatile memories of the DAC so that the MCU may access the DACs memories (non-volatile and/or volatile memories). The mixed signal integrated circuit device has a user programmable address.
