Abstract

A low distortion feed forward delta sigma modulator includes a first adder configured to receive a feedback signal and an input signal. The modulator also includes a first integrator configured to receive an output from the first adder, and a second integrator configured to receive an output from the first integrator. The modulator further includes a second adder configured to receive a second integrated path from the second integrator, a first integrating path from the first integrator and a first summing path from the input signal. The modulator also has a last integrator configured to receive an output from the second adder.
