  • Patent number: 10700691
    Abstract: A circuit includes a first external terminal, a first lower resolution analog-to-digital converter (LRADC) coupled to the external terminal and configured to perform a first conversion of an analog signal received at the external terminal to a digital value, and a higher resolution analog-to-digital converter (HRADC). The HRADC is configured to selectively receive the analog signal from the first external terminal based on the digital value. When the digital value outputted by the first LRADC indicates a change in value of the received analog signal, the HRADC is provided with the analog signal and performs a second conversion of the analog signal to a second digital value. The first LRADC has a lower conversion resolution as compared to the HRADC.

  • Patent number: 10690730
    Abstract: Switching circuits controllable to force an input into a circuit and to sense a responsively produced output in multiple ways to produce different combinations of positive and negative polarities of a desired signal and of sources of offsets and 1/f noise. The switching circuits are controlled in a non-ordered time sequence of different combinations of positive and negative polarities of the sources of the offsets and 1/f noise that spreads their energy to a frequency range above the desired signal frequency band. The non-ordered time sequence leaves the polarity of the desired signal unchanged. Uncorrelated delta-sigma modulators may generate the control signal. A DSP processes a resulting spectrum of a digital domain version of the sensed output to measure residual offsets and 1/f noise and adds to an input present at the DSMs a signal equal in magnitude and opposite in sign to the measured residual offsets and 1/f noise.

  • Patent number: 10673449
    Abstract: A digital-to-analog converter has both a plurality of DAC stages and a plurality of dummy stages. Each DAC stage causes a glitch or disturbance to a pair of reference voltages when the DAC stage changes its switching state. Each dummy stage also causes a similar glitch or disturbance to the pair of reference voltages when the dummy stage changes its switching state. The dummy stages are controlled to change their switching state responsive to how many DAC stages change their switching state such that a total glitch induced onto the reference voltages remains substantially constant across a succession of digital words converted by the digital-to-analog converter into an analog output signal.
