ABSTRACT:
A novel compensation device for conditioning or generating signals to have an arbitrarily defined shape, produced to an arbitrarily specified accuracy. The device comprises a plurality of bounded polynomial function generators having outputs summed into a summing network to produce a signal which is the composite of the effects of all of the polynomial generators. Accuracy is achieved through the use of fusible link trimming of the compensation circuits, which are configured to provide mathematically well-behaved polynomial functions with predictable responses to the programming, and which produce effects only over desired segments of the range of interest. The result is a monotonic signal with no discontinuities, which can be made arbitrarily close to a specified signal.
