Testable ASIC design for a fuzzy logic based QRS complex detector

This paper presents an approach towards implementing a QRS detection algorithm into a single chip environment for maternal and fetal heart rate monitoring by using a fuzzy decision method to identify maternal and fetal QRS complexes from single-lead maternal abdominal recordings. A top-down design methodology was adopted during the design of the ASIC. Testability strategies were adopted in order to increase the ASIC reliability.
