Abstract:
1. An amplifier comprising: an interleaved PWM generator providing primary and secondary sets of interleaved PWM pulses in response to an input signal; an interleaved PWM output stage responsive to corrected interleaved PWM pulses corresponding to the primary set of interleaved PWM pulses to generate an amplified PWM output signal; an interleaved PWM corrector coupled between the interleaved PWM generator and the interleaved PWM output stage, the interleaved PWM corrector operable to receive the primary set of interleaved PWM pulses, and the interleaved PWM corrector responsive to one or more correction signals derived from one or more feedforward signals corresponding to the secondary set of interleaved PWM pulses to generate, from the received primary interleaved PWM pulses, the corrected interleaved PWM pulses for use by the interleaved PWM output stage.
