Abstract :
This paper presents the design of an off-chip supply current monitor for the detection of faults in analogue circuits. The emphasis is placed on the design of a monitor with minimum overhead that can be implemented to detect variations in the dynamic supply current. The design of the monitor and the results of using it to detect faults in an analogue circuit, in both simulation and physical environments, are outlined.
