Abstract: An apparatus having an analog-to-digital converter with an increased effective resolution is disclosed. The apparatus includes a signal processing functional block and an analog-to-digital conversion block. The signal processing functional block includes a controller for providing a set of digital control signals according to a set of digital input signals received by the controller, a digital-to-analog converter for converting the digital control signals to a set of corresponding analog control signals, and a physical hardware unit for performing a specific function according to the analog control signals. The analog-to-digital conversion block includes an adder for adding a dither signal to an analog feedback signal originated from the physical hardware unit, an ADC for converting sums of dither signals and analog feedback signals to a set of oversampled digital control signals to be fed into the controller.
