  • Dynamic brown-out threshold voltage for power control
    Patent number: 9812948
    Abstract: A method of operating a power up circuit is disclosed. The method includes receiving an input voltage and creating a plurality of sample voltages from the input voltage. One of the sample voltages is selected and compared to a reference voltage. The power up circuit produces a brown-out signal in response to the step of comparing.
    Type: Grant

  • Analog-to-digital converter
    Patent number: 9240801
    Abstract: A delta sigma analog-to-digital converter (ADC) providing optimized performance and energy consumption. In one embodiment, a delta-sigma ADC includes a loop filter and a multi-bit quantizer. The multi-bit quantizer is coupled to the loop filter. The quantizer includes a counter, a reference voltage generator, and a comparator. The counter is configured to provide a multi-bit output value that estimates an output of the loop filter. The reference voltage generator is configured to generate a reference voltage ramp based on the output value of the counter. The comparator is coupled to the reference voltage generator to compare the reference voltage ramp to output of the loop filter.
