Abstract:
A noise suppression circuit comprising:an internal circuit having high and low level terminals wherein the low level terminal is connected to a low level power supply line; a first transistor, wherein one main electrode is connected to the high level terminal of the internal circuit, wherein when said internal circuit is active, the first transistor is conductive, and wherein when said internal circuit is inactive, the first transistor is not conductive; a bypass capacitor connected between the other main electrode of the first transistor and said low level power supply line; a second transistor which is connected between the other main electrode of said first transistor and a high level power supply line, and is not conductive when said internal circuit is active, and is conductive when said internal circuit is inactive; and a first resistor connected between the high level terminal of said internal circuit and said high level power supply line.
