Abstract
Fault detection in linear bipolar integrated circuits using power supp ly current measurements is investigated. The most prevalent, catastrop hic and parametric faults, have been modelled for a representative (74 1 type) opamp. The circuit is simulated under both linear and nonlinea r operation. Comparative results between power supply current and outp ut voltage measurements are given, showing the improvement in fault co verage by the use of the current sensing method.
