Abstract

Circuit for providing drive signal waveforms. The circuit includes a current mode logic (CML) driver that includes a common mode voltage (VCM), an output node and a complementary output node. The circuit also has a level shifting mechanism that is coupled to the CML driver. The level shifting mechanism adjusts the common mode voltage (VCM) by either drawing a level shifting current from the output node and the complementary output node or injecting a level shifting current into the output node and the complementary output node.
