| Zusammenfassung: | A feedback apparatus includes a current amplifier for generating a binary error signal corresponding to a received feedback signal, a switched capacitor filter, coupled to the current amplifier, for averaging the binary error signal and providing a voltage reference corresponding thereto, and an output stage, coupled to the switched capacitor filter and to the current amplifier, for outputting a current corresponding to a magnitude of the voltage reference and for providing the feedback signal to the current amplifier. |
