Abstract:
A small amplitude signal output circuit comprising:a first output section having a first transistor of a first conductivity type and a second transistor of a second conductivity type connected in series between a first source line and a second source line, said first output section receiving a first logic signal to output a first output signal through a first node connecting said first transistor and said second transistor; anda first voltage control section connected between said first source line and said first transistor for reducing a supply voltage for said output section;wherein said voltage control section comprises a third transistor and a first diode connected in series between said first source line and said first transistor, and at least one second diode and a resistor connected in series between said first diode and said second source line, and wherein a second node connecting said at least one second diode and said resistor is connected to a control electrode of said third transistor.
