Novel TSC CMOS circuit
Jeong Beom Km · 2009
Totally self-checking (TSC) circuit is a class of circuits which are used to detect faults concurrently with normal operation. This paper introduces a new method for designing self-checking static CMOS circuit. The designed circuit based on the proposed method can detect breaks and transistor stuck-on faults. The resulting circuit produces a valid code (00 or 11) on its output in the fault-free. Otherwise, this circuit produces an invalid code (01 or 10) on their outputs in the presence of such faults. The validity and effectiveness are verified through the HSPICE simulation.
