ABSTRACT:
An operational amplifier circuit having a phase-compensating capacitor disposed between the output of an amplifier circuit as a first stage and the output of an amplifier circuit as a second stage is provided with a potential holding circuit for maintaining the potential at a node A between the first and second stages at a given value so as to control a drop in the potential at the node A, thereby making it possible to prevent a response delay from occurring in a transition waveform of an output from the second stage upon the charging of the phase-compensating capacitor.
