ABSTRACT:
A multistage operational amplifier designed as an IC chip, with a large feedback resistor inserted between its output terminal and its inverting input terminal, is provided with an external voltage divider between the output terminal and ground, this divider including a larger ungrounded resistor and a smaller grounded resistor. The junction between these two resistors is capacitively returned to the inverting input terminal.
