Abstract:
1. A low distortion feed forward delta sigma modulator, comprising: a first adder operable to receive a feedback signal and an input signal; a first integrator operable to receive an output from the first adder; a second integrator operable to receive an output from the first integrator; a third integrator operable to receive an output from the second integrator; a second adder operable to receive a second integrated path from the second integrator, a first integrating path from the first integrator, a first summing path from the input signal, a second summing path from the first integrator, and an output from the third integrator; a last integrator operable to receive an output from the second adder; and a quantizer operable to feedback output to the first adder and also outputting from the low distortion feed forward delta sigma modulator.
