  • Patent number: 10511325
    Abstract: Aspects of dynamic data compression selection are presented. In an example method, as uncompressed data chunks of a data stream are compressed, at least one performance factor affecting selection of one of multiple compression algorithms for the uncompressed data chunks of the data stream may be determined. Each of the multiple compression algorithms may facilitate a different expected compression ratio. One of the multiple compression algorithms may be selected separately for each uncompressed data chunk of the data stream based on the at least one performance factor. Each uncompressed data chunk may be compressed using the selected one of the multiple compression algorithms for the uncompressed data chunk.

  • Patent number: 10505561
    Abstract: A dither is an uncorrelated signal, usually pseudo-random noise injected into the input of an ADC such that a given input value of the wanted signal becomes spread over a plurality of codes. This reduces the effect of DNL and also smooths the integral non-linearity (INL) response of the ADC. The advantages of introducing dither could be obtained without having to perturb the signal input to the ADC. This avoids the introduction of additional components in the ADC. The dither can be applied to the components used to form a residue of the ADC stage within a pipelined converter. For example, a dither can be applied solely to a DAC part or different dithers can be applied to a ADC and DAC parts respectively. This allows greater flexibility of linearization of the ADC response and the formation of an analog residue by the DAC.

  • Patent number: 10503122
    Abstract: Systems and methods are described for determining a phase measurement difference between a received modulated signal and a local clock signal. An adjusted local clock phase measurement may be determined by subtracting, from the phase measurement difference, a phase correction that is based on the frequency difference between the modulator signal's carrier frequency and the local clock's frequency. A phase modulation value may be generated by scaling the adjusted local clock phase measurement. The scaling may be based on a ratio of the modulated signal's carrier frequency and the local clock's frequency. The phase correction may be based on (i) a count of periods of the modulated signal occurring between each corrected phase measurement and (ii) a difference between the carrier frequency and the local clock frequency.

  • Patent number: 10491237
    Abstract: A continuous-time delta-sigma modulator includes a loop filter, a quantizer, a finite impulse response (FIR) filter, and a digital to analog converter. The loop filter integrates a difference between an input signal and a feedback signal. The quantizer quantizes a signal output from the loop filter to convert the quantized signal into a digital signal. The FIR filter performs an FIR filtering process on the digital signal output from the quantizer. The digital to analog converter converts a signal output from the FIR filter into an analog signal and outputs the converted analog signal as a feedback signal.

  • Patent number: 10491234
    Abstract: A system includes a central processing unit (CPU) core, and a pulse width modulator (PWM) controller configured to generate a PWM control signal having a PWM cycle. The system also includes an analog-to-digital converter (ADC), an accumulator, a sum register, and an oversampling register set.

The time spacing between consecutive digital samples varies among the specified time points. The accumulator accumulates digital samples from the ADC and stores an accumulated sum in the sum register. The CPU core reads the accumulated sum from the sum register, and can use the accumulated sum to calculate a metric (e.g., an average) of the digital samples.

  • Patent number: 10461866
    Abstract: In a modulation system that modulates and transmits an optical signal over at least one optical fiber in response to an input digital data word of N bits, there is an input enabled for receiving the digital data word; an electrically controllable modulator having one or more waveguide branches, where each branch receives an input of an unmodulated optical signal; and a digital to digital converter enabled for converting the N bits to a digital drive vector corresponding to M drive voltage values, where M>N and N>1. The electrically controllable modulator couples the drive voltage values to the unmodulated optical signal(s). The coupling enables pulse modulation of the unmodulated optical signal(s) thereby generating pulse modulated optical signal(s). The electrically controllable modulator outputs the pulse modulated optical signal(s) to one or more outputs that are enabled for transmitting the pulse modulated optical signal(s) over at least one optical fiber.

  • Patent number: 10454492
    Abstract: A conversion time and an acquisition time of an ADC can be estimated so that a speed of the ADC can be calibrated. An ADC circuit can perform M bit-trials in its conversion phase and continue performing additional bit-trials in a calibration mode. The ADC can count the number of additional bit-trials performed, e.g., X bit-trials, that occur before the next conversion phase, where additional bit-trials can be considered to be the number of available bit-trials during an acquisition time if the ADC continues performing bit-trials instead of sampling an input signal. The ADC can estimate the conversion time and the acquisition time using M and X. Then, the conversion time of the ADC can be calibrated by adjusting one or more of the comparison time, DAC settling delay, and logic propagation delay.

In one aspect, a multiple-bit parallel SAR ADC circuit includes a number of SAR controller circuits, each of which includes SAR register circuits. Each SAR register circuit receives and stores a corresponding digital bit that is based on a comparison of an analog input signal and a corresponding digital-to-analog converter (DAC) analog signal. Each SAR register circuit also provides a corresponding digital signal based on the digital bit. A DAC circuit receives a reference voltage, and uses the reference voltage and a subset of digital signals generated by SAR controller circuits to generate multiple DAC analog signals. A compare circuit generates the digital bit corresponding to each SAR controller circuit, wherein a number of the digital bits are generated in parallel. Each digital bit collectively forms a digital representation of the analog input signal.
