| Popis: | This paper presents a switched capacitor technique for bus-pumping compensation in a half-bridge class-D amplifier. The proposed approach, in addition to the almost complete reduction of the bus-pumping eect, allows the half-bridge class-D amplifier to preserve maximum energy eciency. The studied hardware implementation of the proposed technique demonstrates its advantages of high eciency, simple circuit, and low cost. The principal design and operating principles are analyzed and described. The experimental static characteristics and time-domain waveforms for the proposed technique are shown to verify its feasibility. |
