Abstract: Provided is an analog to digital converter configured to receive a continuous input signal. The analog to digital converter includes an integrating block, comprising at least an integrating stage, which output is coupled to a flash analog to digital converter. The analog to digital converter apparatus includes a feedback path coupled to the output of said flash analog to digital converter. The feedback path includes at least a digital to analog conversion block which output is compared at least to the input signal to obtain an error signal which is brought as input to said integrating block. A control block is configured to perform control comprising at least a digital integration, is coupled between the output of said flash analog to digital converter and said feedback path.
