摘要：PROBLEM TO BE SOLVED: To reduce the generation of noise within a chip and to exclude influences of the noise on an analogue circuit on the chip or the like by suppressing an output amplitude of an output buffer. SOLUTION: A small amplitude output buffer 10 is constituted by inserting a PMOS transistor which is diode-connected, an inverter 13 and a diode connected NMOS transistor 12 serially between a power source VDD and a ground VSS and by connecting a resistance element 14 between a power source terminal and a ground terminal of the inverter 13.
