Abstract:
A driver circuit comprising:a first current source transistor, one end of the first current source transistor being connected to a first standard power source, a gate of the first current source transistor being applied with a bias potential for stabilizing fluctuations in current from said first standard power source;a second current source transistor, a gate of the second current source transistor being connected to the other end of said first current source transistor, the other end of the second current source transistor being connected to a second standard power source;first and second output transistors connected in series between the other end of said first current source transistor and one end of said second current source transistor;third and fourth output transistors connected in series between the other end of said first current source transistor and one end of said second current source transistor, the third and fourth output transistors being connected in parallel with said first and second output transistors;a first output terminal provided between said first and second output transistors;a second output terminal provided between said third and fourth output transistors;a terminal resistance provided between said first and second output terminals; andclamp circuits provided at both ends of said terminal resistance.
