Abstract
A driver circuit includes a driver array configured to generate, at a first output, a multi-bit output signal including a first bit associated with a predetermined first-bit amplitude and a second bit associated with a predetermined second-bit amplitude. The driver array includes first-bit driver slices coupled in parallel between a first input of first data associated with the first bit and the first output, and second-bit driver slices coupled in parallel between a second input of second data associated with the second bit and the first output. A first ratio between a first number of enabled first-bit driver slices and a second number of enabled second-bit driver slices is different from a second ratio between the predetermined first-bit amplitude and the predetermined second-bit amplitude.
