ABSTRACT:
A method and circuit includes a means for reducing hysteresis in a system. The method includes the definition of boundary conditions relative to an incoming signal. The boundary conditions and the incoming signal are then utilized to determine a proper correction value. The hysteresis correction value is tailored to changes in the input signals. The modification occurs because the boundary conditions are changed depending on the input signal such that the correction values are constantly and continuously varied and implemented to accommodate changes in the input value. The constant accommodation and changing of the correction value provides a simple and effective hysteretic error accommodation that yields a substantially free hysteresis signal.
