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.
