Abstract

Fault-tolerant design of analog circuits is more difficult than that of digital circuits. Chatterjee (1993) has proposed a continuous checksum-based technique to design fault-tolerant linear analog circuits. However, some faults in the passive elements cannot be detected if the checker has not been designed appropriately. This paper addresses the fault coverage issue in the continuous checksum based technique and proposes an error signal analysis based method for improving fault coverage of the checker
