Patent ID: 7019729

Claim:
A driving circuit comprising: a first differential circuit, connected between a first voltage source and a second voltage source, receiving a prescribed reference voltage and including a first through current control transistor; a second differential circuit, connected between said first voltage source and said second voltage source, receiving said prescribed reference voltage and including a second through current control transistor; and an output circuit including a first conductivity type first output transistor having a gate supplied with an output of said first differential circuit and a second conductivity type second output transistor having a gate supplied with an output of said second differential circuit; wherein a first potential is supplied to the gate of said first through current control transistor of said first differential circuit while a second potential is supplied to the gate of said second through current control transistor of said second differential circuit; and the potential of a prescribed node of said second differential circuit is supplied to the gate of said first through current control transistor of said first differential circuit, and a prescribed bias potential is supplied to the gate of said second through current control transistor of said second differential circuit.
