ABSTRACT:
An offline trim circuit includes one or more irreversible trim elements, such as fuses, for example, used for setting electrical parameters to desired values. Associated circuitry is employed to verify the effect of trimming, prior to permanently setting trim bit values, permitting the optimal definition of the trim bit sequence and completely eliminating guesswork from the trimming procedure.
