METHOD AND DEVICE FOR A DELTA SIGMA ADC WITH PARALLEL COUPLED INTEGRATORS

摘要

A delta-sigma modulator having an output port comprising: at least two first-stage integrators connected in parallel; a second-stage integrator connected in series with the first-stage integrators; one quantizer connected to the integrator of the second Step connected in series; andat least two digital-to-analog converters, wherein a first digital-to-analog converter is coupled between the output of the delta-sigma modulator and an input of a first integrator of a first stage, and a second digital-to-analog converter is coupled between the output of the delta Sigma modulator and an input of a second integrator of a first stage is coupled.
