Abstract
A driver circuit includes a differential input, a differential output, a bias node, a first T-coil having a first node coupled to the negative output node and a second node coupled to a source of supply voltage, a second T-coil having a first node coupled to the positive output node and a second node coupled to the source of supply voltage, a first transistor having a current path coupled between the center tap of the first T-coil and a first intermediate node, a second transistor having a current path coupled between the center tap of the second T-coil and a second intermediate node, a third transistor having a current path coupled between the first intermediate node and ground, and a fourth transistor having a current path coupled between the second intermediate node and ground.
