Abstract
The present invention provides technical advantages as a class AB output driver ( ) with minimal cross-over distortion. If the differential input to the driver is I+&dgr;I/2 and I−&dgr;I/2, then the current gain is the average of &bgr; and &bgr; , more specifically, (&bgr; −&bgr; )*I+((&bgr; +&bgr; )/2)* &dgr;I. The offset current (&bgr; −&bgr; )*I is taken out with a feedback loop.
