Abstract
Techniques to provide a replica bias circuit for a high speed and low voltage common mode driver. In an embodiment, a pre-driver is coupled to provide driver input voltages to the driver, which driver includes a set of circuit elements coupled to provide, based on the driver input voltages, an output signal of a differential output. In another embodiment, a regulator circuit is coupled to provide regulated power to the pre-driver and driver, where the regulator circuit includes a scale replica circuit having a replica of the first set of circuit elements.
