Abstract

PURPOSE:DC reference voltage is piled up on audio signal to obtain high-frequency pulse signal responding to voltage change. With this pulse signal, switching is performed to convert into amplification waveform. Thus, a simple structure amplifier can be secured, through which the signal in broad band can be amplified with high efficiency.
