Abstract
A driver circuit is provided. The driver circuit includes a differential driver, a first feedback passive circuit and a second feedback passive circuit. The differential driver includes a first half circuit and a second half circuit. The first half circuit has a first input point and a first output point. The second half circuit has a second input point and a second output point. The first feedback passive circuit is coupled to the second input point and the first output point. The second feedback passive circuit is coupled to the first input point and the second output point.
