More Information
Summary:The utility model relates to a complementary power amplification circuit, comprising an input circuit used for processing and amplifying an input signal and a feedback signal, and sending the amplified signal to a driving upper arm and a driving lower arm; the driving upper arm and the driving lower arm are used for pushing the power upper arm and the power lower arm to output power; the power upper arm and the power lower arm are complementary or quasi-complementary single power tubes or composite power tubes; the current sampling amplitude limiting circuit is used for sampling quiescent current of a power arm and outputting the quiescent current to the current conversion unit in a voltage form; the current conversion unit is used for converting the voltage into a current signal and outputting the current signal to the integral biasing circuit; and the integral bias circuit is used for converting the current signal into bias voltages of the upper and lower arms in a negative correlation manner.
