Abstract :
In this paper, a supply current sensing circuit for detecting feedback bridging faults, which generates oscillations when a sensitized input is provided, is proposed. The circuit consists of an I-V transformer, a high-frequency amplifier and a demodulation circuit. It is shown by some experiments that such bridging faults can be detected with the circuit.
