A new analog parametric self-disconnecting BIC sensor class

We propose a new type of BIC sensor (SD BICS) with the properties described. The sensors work with analog circuits, continuously monitoring a given current. As a particular case, the self-disconnecting BICS (SD BICS) can be applied to digital circuits. The values of the current sensibility are programmable, both at design and functioning time. They are self-disconnecting/connecting, meaning that whether an overshoot current is detected, they disconnect the CUT by lowering (raising) the virtual V_dd (ground) potential. This implies that the circuit is actually cut from the power supply and invokes a negligible power consumption in an erroneous state. If at some moment, the CUT regains its normal functioning state, the SD BICS automatically resumes supervising it. We make theoretical considerations of how to design the SD BICS, give HSpice simulation results and refer to some of the applications
