Abstract
The invention provides an analog-to-digital converter (ADC) converting an input signal to an output signal. The ADC may comprise a main circuit and a comparator coupled to the main circuit. The main circuit may: transfer the input signal by an input transfer block, filter an error signal by a loop filter, and combine the transferred input signal and the filtered error signal to form a combined signal. The comparator may quantize the combined signal to provide the output signal, wherein the error signal may reflect a difference between the combined signal and the output signal.
