摘要： A sigma-delta analog-to-digital converter includes an integrator having an input and an output and an integrator capacitor connected between the input and output. A switched-capacitor input circuit includes at least one input capacitor, an input sampling switching circuit and an input delivery switching circuit. The input sampling switching circuit includes at least one input sampling switch operable to connect the input capacitor to be charged by an input voltage at a sampling rate. The input delivery switching circuit includes at least one input delivery switch operable to connect the input capacitor to transfer charge to the integrator capacitor at a first transfer rate. A switched-capacitor feedback circuit is connected in a feedback path between the input and output of the integrator. The feedback circuit includes at least one feedback capacitor, a feedback sampling switching circuit and a feedback delivery switching circuit. The feedback sampling switching circuit includes at least one feedback sampling switch operable to connect the feedback capacitor to be charged by a feedback reference voltage at the sampling rate. The feedback delivery switching circuit includes at least one feedback delivery switch operable to connect the feedback capacitor to transfer charge to the integrator capacitor at a second transfer rate. The second transfer rate is a predetermined factor greater than the first transfer rate such that the sampled feedback reference voltage charge is transferred to the integrator capacitor at a greater rate than the transfer of the sampled input voltage charge to prevent modulator instability due to an input overload condition.

摘要： A method and apparatus for digital to analog conversion using sigma-delta modulation of the temporal spacing between digital samples. The method and apparatus of the present invention provides for sigma-delta modulation of the time base such that errors produced by nonuniform sampling are frequency-shaped to a region (i.e., shifted to higher frequencies) where they can be removed by conventional filtering techniques In one embodiment, the digital data is interpolated by a fixed ratio and then decimated under control of a sigma-delta modulated frequency selection signal that represents, on average, the data rate of the incoming digital data stream. In another embodiment, the digital data is interpolated under control of a sigma-delta modulated frequency selection signal that represents, on average, the data rate of the incoming digital data stream and then decimated by a fixed ratio. The frequency signal selection number is modulated using an n-th order m-bit sigma-delta modulator. Data thus emerges from the interpolation/decimation process at the clock rate of the n-th order m-bit sigma-delta modulator. The method and apparatus converts the data rate of the incoming digital data stream to the data rate of the n-th order m-bit sigma-delta modulator.

摘要： A method and apparatus for analog-to-digital conversion using sigma-delta modulation of the temporal spacing between digital samples are provided. The method and apparatus include sigma-delta modulation of the time-base such that errors produced by non-uniform sampling are frequency-shaped to a high frequency region where they are reduced by conventional digital filtering techniques. In one embodiment, a sigma-delta ADC receives an analog input signal and converts the analog input signal to digital samples at an oversampling rate. A decimator, coupled to the sigma-delta ADC, receives the digital samples and decimates the digital samples to produce the digital samples at a preselected output sample rate, less than the oversampling rate. An ADC sample rate control circuit, coupled to the ADC, receives a frequency select signal representing the preselected output sample rate, and produces a noise-shaped clock signal for controlling operation of the ADC at the oversampling rate. The control circuit includes a sigma-delta modulator for sigma-delta modulating the frequency select signal. A randomizer/suppressor circuit, under control of the output of the sigma-delta modulator, receives an input clock signal and adjusts the frequency of the clock signal to produce a noise-shaped clock signal for controlling the oversampling rate of the ADC.

摘要： A digital oversampling digital-to-analog converter system includes an interpolator, a sigma-delta modulator, a digital-to-analog converter and a low pass filter. The interpolator receives a digital input signal and upsamples the input signal by certain upsampling factor. The upsampled signal is processed by the sigma-delta modulator, converted to an analog signal by the digital-to-analog converter and then filtered by the low pass filter. The interpolator includes control circuitry, preferably a central processor, which controls the upsampling factor and increases the upsampling factor upon a decrease in the frequency of the input signal.
