Abstract:
A method of an electronic device includes: providing a capacitive digital-to-analog converter having a reference voltage input; providing a reference voltage providing circuit to generate a reference voltage to the reference voltage input of the capacitive digital-to-analog converter; and, generating a compensation signal into the reference voltage input of the capacitive digital-to-analog converter in response to at least one switching of at least one capacitor in a switchable capacitor network of the capacitive digital-to-analog converter.
