    摘要: A driving circuit for driving a diode includes at least one differential pair including a first output node and a second output node and configured to switch an output current, a current source configured to adjust the output current, a dummy load coupled to the second output node, a first termination resistor coupled between the first output node and a termination ground, and a second termination resistor coupled between the second output node and the termination ground. The output current is supplied to the diode through the first output node by at least one differential pair.
