Abstract

PURPOSE:To the feedback circuit of an amplifier, a filter circuit for out-band frequency absorption is provided in order to prevent the oscillation of the amplifier without causing external feedback at the out-band frequency and in order to neutralize the internal feedback of the amplifier within the band, thereby stabilizing the operation of the amplifier.
