Abstract
PURPOSE:To prevent malfunction of an analog circuit, by providing a by-pass capacitor for eliminating a voltage fluctuation generated inside a digital circuit. CONSTITUTION:There is provided a power supply line 5E to which the ground potential GND is externally applied through a power supply terminal 4E and a capacitor C is connected between the power supply line 5E and a power supply line 5D. Therefore, even if a voltage fluctuation is generated in the power supply line 5D by switching operation in a digital circuit 3, a portion of the voltage fluctuation escapes through the capacitor C, the power supply line 5E and the power supply terminal 4E. As a result, a propagation amount to the side of an analog circuit 2 by a floating capacitance FC is reduced by the voltage fluctuation and it is possible to prevent malfunction of an analog circuit.
