Patent ID: 8847682

Claim:
A method for attenuating non-linear noise in an open-loop amplifier, the method comprising: receiving a source signal; generating a first control input signal and a second control input signal from the source signal, wherein the first control input signal and the second control input signal are together representative of the source signal; generating a first control output signal by processing the first control input signal, and generating a second control output signal by processing the second control input signal; providing an effective timing offset between respective edge transitions of the first control output signal and the second control output signal by delaying in time said processing the first control input signal relative to said processing the second control input signal; and generating an amplified version of the source signal by: controlling a first set of switches with the first control output signal; and controlling a second set of switches with the second control output signal, wherein said delaying comprises: generating a first ready signal based on a frame counter clocked with a first clock signal also used for processing the first control input signal; and generating a second ready signal based on a frame counter clocked with a second clock signal also used for processing the second control input signal; wherein the first control signal is not processed until the first ready signal is asserted, and wherein the second control signal is not processed until the second ready signal is asserted.
