  • Self-modulated voltage reference
    Patent number: 8547135
    Abstract: A self-modulated voltage reference circuit may generate a reference voltage by receiving an internal reference voltage of a programmable device at a first input of a comparator block of the programmable device, receiving a feedback voltage at a second input of the comparator block, generating a pulse density modulated (PDM) signal based on a difference between the reference voltage and the feedback voltage, outputting the PDM signal at a digital output pin of the programmable device, and filtering the PDM signal to generate the output reference voltage.
