This paper discusses the challenge of designing window comparators for analog online testing applications. A programmable window comparator with adaptive error threshold is presented. Experimental results demonstrate that improved fault detection capability is achieved by using the proposed design. Measurement results of the fabricated comparator circuit are also presented.
