Abstract
The disclosure describes devices and methods for implementing impedance matching. The device may be implemented on an integrated circuit that includes a communication protocol interface circuit, a first signal output terminal, a first output driver circuit, and a controller. The first output driver circuit is coupled to the controller and has a corresponding plurality of parallel driver stages, each driver stage including a driver and a configurable resistance coupling an output of the driver to the first signal output terminal (e.g., first contact). The configurable resistances of the first output driver form a first series terminated resistance. The controller is configured to adjust the configurable resistances to adjust the first series terminated resistance.
