Abstract
A comparator circuit is provided that determines whether a given value is within a selected compare range. The comparator circuit electronically implements a Ling Adder algorithm to perform comparisons. The circuit operates at a high speed and requires fewer components compared to circuitry implementing a conventional carry look ahead algorithm. The circuit may be implemented in CMOS technology.
