Abstract

PURPOSE:To obtain a high-quality low frequency, by power amplifying a high frequency modulated wave. CONSTITUTION:The negative feedback NFB of a low frequency region at a low frequency amplifying stage, and at the same time the feedback NFB of a high frequency region is applied at a high frequency amplifying stage respectively for an amplifier that amplifies the power of a high frequency modulated wave. Thus the modulating characteristics are increased by the negative feedback of the low frequency region, and at the same time the overall characteristics are also enhanced. Furthermore the AC amplitude becomes equivalent to a linear element in terms of the input-to-output linearity, i.e. a low frequency owing to the negative feedback of the high frequency region.
