Claim Text:
1. A system, comprising: an adjustable current source; a reference voltage generator to generate a reference voltage at a node, the node to receive injected current from the adjustable current source, a change in a magnitude of the injected current to result in a change in a magnitude of the reference voltage; and a first adjustable resistance and a second adjustable resistance, a first end of each of the first adjustable resistance and the second adjustable resistance coupled to the node, a second end of each of the first adjustable resistance and the second adjustable resistance being selectively coupleable to a first power supply voltage or a second power supply voltage based on a common control signal, the magnitude of the reference voltage at the node being between a magnitude of the first power supply voltage and a magnitude of the second power supply voltage.
