| Abstract: | The function of the bootstrap-capacity in the complementary push-pullpower amplifier is deeply analysed and discussed, and is tested in experiment. The resultsshow that :The bootstrap-capacity has the functions of extending dynamic range of thecircuit,raising the gain of the power amplifier current and that of the voltage-amplifierstage,raising the efficiency of the power amplifier and improving circuit characteristic. |
