Abstract

PURPOSE: To eliminate the erroneous function caused through the employment of DC amplifier, by connecting a peak hold circuit to the next stage in a DC amplifier and deciding the level of each output through a differential amplifier.
CONSTITUTION: A peak hold circuit F1 is provided at the next stage of DC amplifier A1 to compare the level voltage Vp from said peak hold circuit F1 with the output VO from DC amplifier A1 thus to produce the difference as the output voltage Voc. When employing a differential amplifier E1 and a peak hold circuit F1, the output corresponding with the amplified signal can be obtained without any influence on any bias point.
