High-efficiency high-swing Voltage Mode Logic driver systems and methods

A push-pull assisted voltage mode logic (VML) driver circuit comprising:

• an input to receive an input signal;
• a primary current generator circuit configured to use a supply voltage to generate a primary current;
• a switching circuit coupled to the primary current generator circuit, the switching circuit configured to provide the primary current to an output node including a termination resistance, the output node configured to generate a first output voltage according to the input signal;
• and
• a supplementary current generator circuit coupled to the switching circuit, the supplementary current generator circuit comprising an operational amplifier circuit configured to generate a secondary current to the termination resistance, wherein the switching circuit is further configured to combine the secondary current with the primary current to increase an amplitude of the first output voltage by an amount substantially equal to the secondary current multiplied by the termination resistance.
