Abstract: Methods, systems, and devices for mitigating supply noise in single-ended current mode logic (CML) transmitters are described. A first current source may generate a first bias current for a first differential transistor pair included in a CML transmitter, and a second current source may generate a second bias current for a second differential transistor pair. The first differential transistor pair may route the first bias current through either leg of the first differential transistor pair based on a polarity of an input signal and the second differential transistor pair may route the second bias current through either leg of the second differential transistor pair based on the polarity of the input signal. Based on a first polarity, the second bias current may be routed to a ground reference, and based on a second polarity, the second bias current may be routed through the first differential transistor pair to modify a load current internal to the CML transmitter.
