Abstract

PURPOSE:To obtain an audio amplifier of which structure is simple and economical, by means of installing the first amplification circuit which amplifies the low frequency component and the second amplification circuit which amplifies the high frequency component and reduces the phase gap and the output in parallel, thereby providing the negative feedback to the amplifier as a whole.
