    摘要: In accordance with a preferred embodiment, a self-calibrated cell (and corresponding operation) is provided that receives a reference parameter (e.g., current, voltage, etc.) for storage in the cell and for supplying to a load. The individual cell is controlled to operate in different states or modes: either a redundant mode or a supplying mode. In the redundant mode, the reference parameter is stored in the current cell during a calibration phase or mode, and the stored reference parameter is dumped or otherwise transferred, preferably to ground, during a dumping state or mode. In the supplying mode, the current cell transfers or supplies the stored reference parameter to the load. The individual cell is controlled to operate in its dumping state both before the cell enters the calibration mode and also at the same time that the cell is switched from the calibration mode to the supplying mode. In accordance with a preferred embodiment, the individual cells may be employed in a cell array of a converter (e.g., digital-to-analog converter). All of the cells in the array may individually be placed in a redundant mode in succession, while the remaining cells are in a supplying mode.

    摘要: Embodiments of the present invention provide a passive radio frequency identification (RFID) moisture sensor. This moisture sensor includes one or more antenna structures having a tail. The tail is operable to transport a disturbance such as, but not limited to fluid or moisture from a monitored location wherein the antenna has an impedance and varies with proximity to the disturbance. An integrated circuit couples to the antenna structure. This IC includes a power harvesting module operable to energize the integrated circuit, an impedance-matching engine coupled to the antenna, a memory module, and a wireless communication module. The impedance-matching engine may vary a reactive component to reduce a mismatch between the antenna impedance and the IC and produce an impedance value (sensor code) representative of the reactive component impedance. The memory module stores the impedance value (sensor code) until the wireless communication module communicates with an RFID reader and sends the impedance value/sensor code to the RFID reader. The RFID reader may then determine an environmental condition such as the presence of moisture or fluids at the tail of the RFID sensor. This sensor may deploy several antenna and/or tails sensitive to unique disturbances. These tails may be used to monitor different locations as well as different types of fluids. In one particular embodiment, the disturbance is a fluid or moisture within the gutter of a vehicle body.

    摘要: A method and apparatus for capacitance multiplication using two charge pumps. A first charge pump (206) provides a current signal (1216) that is first conducted by a resistor (310) of an RC network and then split into three current paths prior to being conducted by a capacitor of the RC network. A first current path provides current to the capacitor (306) of the RC network from node (320). A second current path multiplies the current conducted by capacitor (306) by a first current multiplication factor. A third current path provides current to a second charge pump, which multiplies the current from the first charge pump by a second current multiplication factor that has a fractional value with an inverse magnitude sign relative to the first current multiplication factor. The combination of the second and third current paths effectively multiplies the capacitance magnitude of capacitor (306).

    摘要: Combined echo and crosstalk cancellation is provided. Frequency domain adaptive filters are used to remove or reduce the effects of echo and crosstalk for a multi-channel and full-duplex communications system. Data from each transmit channel is buffered and converted to the frequency domain. The frequency domain data is multiplied by crosstalk coefficients to obtain a frequency domain correction signal for each channel. Adaptation of the crosstalk coefficients is based on correlations between the error signals and the data from each of the transmit channels. A single frequency domain transform engine, such as a Fast Fourier Transform engine, is employed for all calculations to save power and area.
