Abstract
An analog to digital converter includes a delta sigma modulator with a modified distributed feed-forward (DFF) topology. The modulator includes low pass filter circuitry that provides a first path to a first integrator and a second, feed-forward path to a second integrator that significantly reduce the out of band signal transfer function (STF) peaking of the modulator.
