摘要： PURPOSE:To restrain a switching noise caused by an inductance component by a method wherein the phase of the output of a first buffer circuit is constituted to be completely opposite at a rise and at a fall and the phase of the operation of a second buffer circuit is constituted to be completely opposite to that of the first buffer circuit. CONSTITUTION:One end of a load capacity is connected to the output end of a buffer circuit 7; a power-supply voltage VSS is supplied to the other end of the load capacity 8. The buffer circuit 7 is constituted so as to be operated at a phase which is completely opposite to that of a buffer circuit 4. That is to say, the input signal of the buffer circuit 7 is the inverse of a signal Vin of the signal Vin of the buffer circuit 4. A bypass capacity 6 is connected in parallel with the buffer circuits 4, 7, and power-supply voltages VDD1, VSS1 inside a circuit device are applied to it. Inductances 2, 10 caused by lead wires or the like in a package exist between the external power supply and the internal power supply of the circuit device. A noise generated in the power supply is offset by adding the buffer circuit 7 and the load capacity 8 whose phase is opposite.

摘要： PURPOSE:To suppress switching noise due to an inductance component of a power source supply unit by disposing to form a capacitor or a groove-shaped capacitor in which power source layers having different potentials are alternately laminated through insulators, near a power source line in a chip. CONSTITUTION:An input/output circuit has a P-channel transistor 2 and an N-channel transistor 3 formed on a semiconductor substrate 1, a high potential power source layer 7 is disposed to be formed on a part directly above the transistor 2 and a low potential power source layer 9 is disposed to be formed on a part directly above the transistor 3. The layers 7, 9 are insulated by an insulating film, and connected by a protrusion 11 formed at a power source layer adjacent side. Thus, a capacitor having a relatively large capacity is formed without increasing the area of a chip, and connected to a power source near the input/output circuit. Accordingly, an inductance component between the circuit and the capacitor can be suppressed to a small value.
