A current mode logic buffer includes a differential pair of input transistors comprising a first input transistor and a second input transistor, a first output load resistor coupled in series with the first input transistor, a second output load resistor coupled in series with the second input transistor, a first output at a first node between the first output load resistor and the first input transistor, a second output at a second node between the second output load resistor and the second input transistor, a first hold capacitor configured to provide a semi-constant voltage source to the first output via a first low-resistance path, and a second hold capacitor configured to provide a semi-constant voltage source to the second output via a second low-resistance path.
