ABSTRACT:
Various systems and methods for drift compensation are disclosed. As one example, a system for compensating drift in a control circuit is disclosed that includes at least two control signals. One of the control signals is provided by a circuit that is susceptible to drift. This control signal is provided both to a systems or device under control, and to a detection circuit. The detection circuit is operable to detect a drift in the control signal. In addition, the detection circuit provides another control signal that varies as a function of the drift in the received control signal.
