Reducing the output integrated voltage by repeatedly discharging the integration capacitor through a feedback loop via a digital-to-analog converter generating a feedback pulse, wherein a feedback clock period (T) clk_DAC ) For defining the time interval between successive rising edges of the feedback pulse. At intervals of a number of feedback clock cycles (T) clk_DAC ) In-line with the aboveThereafter, sampling is performed during an extended feedback clock period (T).)
