Abstract: A programmable transmitter circuit may be coupled to a controller circuit. The controller circuit may be configured to generate control signals based at least on a signal. The transmitter circuit may include a plurality of unit cells. Each unit cell may include a respective first current source and a respective second current source. Each unit cell may be configured to be set in an activated state or a deactivated state based at least on the control signals. For a unit cell of the plurality of unit cells, when the unit cell is set in the activated state, the respective first current source or the respective second current source may be configured to generate a current to be applied to a load.
