Abstract
A Delta-Sigma modulator is disclosed, which has a Delta adder, a Sigma adder, a first latch, a second latch and a feedback generator, wherein the feedback generator provides a feedback signal to the Delta adder based on a pre-stage data signal provided by the first latch, so that the Delta adder provides a pre-stage addition signal. The Sigma adder performs an accumulation to provide an accumulative signal to the first latch, so that the first latch provides a pre-stage data signal to the second latch to enable the second latch to output a digital output signal.
