ΔΣ modulation circuit and system
Abstract:
A ΔΣ modulation circuit that includes a first integrator and second integrator coupled in series, a quantizer coupled to an output of the second integrator, a delay device disposed in a feedback path from an output of the quantizer to an input of the first and second integrators, an adder which generates a difference between an output and an input of the quantizer, and a feedback circuit including a delay device which couples an output of the adder to an output of one of the first and second integrators.
