摘要： A successive approximation routine analog-to-digital converter includes a switched-capacitor circuit that samples an input voltage into a plurality of capacitors without the need for power to be dissipated by the analog-to-digital converter. A comparator, coupled to the switched-capacitor circuit, compares a voltage across the capacitors with another voltage during each of a number of iterations. A common mode voltage of the switched-capacitor circuit is boosted during at least some of the iterations. The boost may be accomplished in many different ways and may be different for each of a single-ended, a quasi-differential and fully differential versions of the analog-to-digital converter.

摘要： An analog multiplexer may be used for sampling an input voltage that is capable of having a higher voltage level than an upper supply voltage. The analog multiplexer includes a plurality of input switch circuits and a shorting switch circuit. The plurality of input switch circuits include n-type or p-type laterally diffused field effect transistors (NLDFETs or PLDFETs). At least one of the input switch circuits includes a level shifting switch circuit that is able to sample an input voltage that is greater than the upper supply voltage for the multiplexer. A shorting switch circuit, at an output of the multiplexer, includes a capacitively coupled gate drive circuit and is configured to short a first differential output to a second differential output after the input voltage is sampled.

摘要： A serial protocol and interface for data transmission from a data transmitter 12 to a data receiver 14 where the propagation delay may be up to several clock cycles long and may be varying slowly. The data receiver provides a clock to the data transmitter. A synchronization signal provided by either the receiver or the transmitter initiates a frame of data transmission at a transfer rate controlled by the clock. The synchronization signal coordinates the transmission of a data header followed by a predetermined number of data bits, known as the frame length. The data receiver uses the header bits to determine the times to sample the subsequent data bits. The length of the frame is limited to provide sufficient likelihood the propagation delay line characteristics have not changed enough to cause a bit error. The system resynchronizes at the beginning of each frame.

摘要： An interface system between an RDC and a connected resolver dynamically matches an input range of the RDC to the output range of the resolver's output signals. The interface system may include methods and/or apparatuses to determine the amplitude of sinusoidal input signals presented to the RDC by the resolver and to compare the amplitude against high and low threshold values. A gain control signal may be generated, which may be corrected if the detected amplitude either exceeds the high threshold or falls below the low threshold. The gain control signal may be output to a circuit in the RDC or in the resolver that corrects any mismatch that occurs between the RDC input and the resolver output. For example, the gain control signal may control the amplitude of an excitation signal applied to a primary of the resolver or the gain control signal may be applied to an analog to digital converter at the input of the RDC to control its effective input range.

摘要： Methods and apparatus for jitter and load insensitive charge transfer are disclosed. A quantity of charge is transferred to or from a load during a transfer interval, wherein the charge transferred is significantly insensitive to load characteristics and variations in the transfer interval. A succession of identical or different quantities of charge may be transferred to or from the load during successive transfer intervals. The charge transfer circuit may be employed in mixed switched/continuous-time circuit configurations, and in particular may be used as a unipolar or bipolar one-bit digital-to-analog converter to provide quantized feedback in a sigma-delta analog-to-digital converter circuit configuration. The charge transfer circuit avoids problems of integrating amplifier nonlinearity and input signal distortion in such sigma-delta analog-to-digital converter circuits, and facilitates monolithic fabrication of sigma-delta analog-to-digital converters using standard integrated circuit fabrication techniques.

摘要： A dual channel ADC uses two digital to analog converters (DACs) and a single comparator to convert two analog input channels. One DAC is used for successive approximation, while the other DAC is used for calibration. The dual channel ADC allows for sampling and conversion of single-ended, pseudo-differential, and fully differential analog input signals while maintaining layout symmetry and reducing crosstalk without substantially increasing circuit area. The single comparator is used for converting both analog input channels. Additional logic (such as switches or digital logic) is used to connect the input sampling capacitors and DACs to the appropriate inputs of the comparator for converting the analog input channels.
