  • Analog-to-digital converter with power supply-based reference
    Patent number: 9281833
    Abstract: A measurement circuit is provided for measuring the resistance of a variable resistance element biased with an external voltage supply. The measurement circuit includes an analog-to-digital converter (ADC) and a reference generator connected with the ADC. The ADC is operative to receive a reference voltage and a first voltage developed across the variable resistance element, and to generate a digital output signal indicative of a relationship between the first voltage and the reference voltage. The reference generator is operative to generate the reference voltage as a function of the external voltage supply.
