Abstract
A CML to CMOS signal conversion system includes a CML/CMOS converter coupled to a resistor, which is further coupled to a current compensation circuit at a reference node. The CML/CMOS converter receives a differential signal and applies a first or a second current to the reference node through the resistor. The current compensation circuit comprises a differential transistor pair coupled to a current source, a transistor, and a first, a second, and a third current mirror. The differential transistor pair receives the differential signal and has a pair of output terminals. The first current mirror is coupled to the output terminals. The third current mirror is coupled to the reference node. The first and third current mirror are coupled together by the transistor and sink the first current. The second current mirror is coupled to the output terminals and the reference node and sinks the second current.
