Abstract
An integrated circuit includes a first-stage amplifier circuit and a following-stage amplifier circuit connected in series, a common power source pad for supplying power to the amplifier circuits, and metal wires respectively connecting the common power source pad to the amplifier circuits. On the metal wire which connects the first-stage amplifier and the power source pad, an integrator is electrically connected. This arrangement decreases a coupling noise generated in the first-stage amplifier circuit, thereby stabilizing circuit operation of the following-stage amplifier circuit.
