US Patent 7535391 Analog-to-digital converter having random capacitor assignment and method thereof

An analog-to-digital converter (ADC) includes a multiplying digital-to-analog converter (MDAC) having a plurality of capacitors and a plurality of capacitor positions. The ADC generates a random number for a conversion cycle. The ADC configures each capacitor of the plurality of capacitors in a corresponding capacitor position of the plurality of capacitor positions based on the random number for the conversion cycle. The ADC converts, for the conversion cycle, a voltage of an analog signal to a digital value based on the capacitor configurations.
