The present invention relates to analog-to-digital converters and more particularly to a delta-sigma analog-to-digital converter 1 for generating a digital signal as a function of an analog signal and a clock signal having a first phase and a second phase, said converter comprises:-a first branch 11 for applying an analog input signal,-a feedback branch for feeding back an analog reference signal, with a digital-to-analog converter 121,-a loop filter 13,-a quantizer 15, and-a switch 16, the switch being arranged and timely correlated with an output switch of said digital-to-analog converter in order to connect the input resistance and disconnect the digital-to-analog converter during said first phase and to disconnect the input resistance and connect the digital-to-analog converter during said second phase. The present invention also relates to a method for operating the same. |
