Abstract
A system and method for driving a load at a desired operating level. A driver is connected to a load. The load can be selected from a plurality of loads by a selection system, such as a multiplexer, or a single load can be utilized. Feedback from the load is provided to the driver for achieving the desired operating level. A zero temperature coefficient resistance formed by two resistors having different resistances can be used so that the driver emulates an ideal resistor having a substantially zero temperature coefficient, providing a temperature independent current to the load.
