Abstract: A switching amplifier includes a compensation circuit to compensate for DC offset in the amplifier, to enhance operation of the switching amplifier. The compensation circuit may comprise a SAR ADC, where the DAC element can be used to provide a compensation voltage. The switching amplifier may further include a PWM modulator configured to avoid cross-talk to further enhance operation of the switching amplifier.
