Data drivers

Abstract

This application relates to data driver circuits, in particular to laser drivers. A driver is configured to receive an input signal and generate a corresponding driver output signal for driving an output device, such as a laser. A bias generator has a first output branch connected to an output node of the bias generator and a first control loop is configured to control a current in the first output branch to have a defined relationship to a bandgap referred current to provide a first bias current for biasing the output device. A driver output node is coupled to the driver and also to the output node of the bias generator, for outputting the driver output signal and the first bias current to the output device.

Dependencies are inferred from the claim text.
