Delta sigma modulator

A modulation method for a converter having an input circuit to receive an input signal and an output circuit to provide a converted output signal, the modulation method comprising the steps of:

• receiving a comparator output from an input circuit;
• sampling said comparator output based on a first clock;
• generating a forward pulse to an output circuit based on said first clock;
• generating a feedback signal for said input circuit based on a second clock, wherein said second clock has a lesser frequency than said first clock;
• a Delta Sigma converter, the Delta Sigma converter comprising an input circuit operable to receive an input signal and provide an integrated input signal having a negative feedback loop, and an output circuit operable to receive a modulated output signal and produce a converted output signal, wherein the method comprises the steps of:
• providing a comparator output of an integrated input signal of said input hardware circuit;
• sampling said comparator output, said sampling based on a first clock frequency;
• performing a forward conditioning operation on said sampled comparator output to provide a modulated output signal for said output circuit;
• generating a modulated feedback signal based on said sampled comparator output, said generating based on a second clock frequency;
• and
• outputting said modulated feedback signal to said input circuit,
• wherein said first clock frequency is less than said second clock frequency.
