Abstract:
This ΔΣ modulator is a ΔΣ modulator using multiple integrators. The integrator: includes a plurality of stages of adder sequences, each of the adder sequences including a plurality of adders connected in series; performs feedback of a result of a second adder sequence as an input to a first adder sequence, the first adder sequence being a first stage of the plurality of stages, and the second adder sequence being a last stage of the plurality of stages; and processes inputs supplied to the plurality of adders of the first adder sequence and supplies it to the second adder sequence.
