Abstract:
A delta-sigma modulator is disclosed which has a filter comprising a filter input, two LC resonators (LC1-1, LC1-2), and two switches (CBT/CGT). An input of each one of the two switches is connected to the filter input and a corresponding output of each one of the two switches is connected to a corresponding one of said LC resonators. Each one of the two switches is individually controllable for selectively connecting the corresponding one of the LC resonators with the filter input. The invention also relates to a method for changing the mode of operation of a delta-sigma modulator.
