Abstract
The present invention provides a system () for controlling drive signal timing parameters of an output driver circuit (). The present invention defines a driver circuit having an output interface (), and a first transistor () coupled to a first voltage supply (), a first control signal (), and a first node (). The circuit also has a first resistive element, coupled between the first node and a second node (). A second resistive element () is coupled to ground. A second transistor () is coupled to the second node, to a second control signal (), and the second resistive element. The circuit has a third transistor (), coupled to the first and second nodes, and to a third node (). A third resistive element () is coupled between the third node and the output interface. A fourth transistor () is coupled to the first and third nodes, and to the output interface. The circuit also has a fifth transistor (), coupled to a second voltage supply (), to the first node, and to the output interface.
