Fault Modeling and Testing for Analog Circuits in Complex Space Based on Supply Current and Output Voltage

Figure 5

Distances between and -loci with respect to different fault models. Curve is defined by the 3D model proposed in Section 3, is the 2D model proposed in Section 2, is corresponding to the 3D model proposed in [14], and is corresponding to the complex-circle-based fault model proposed in [12, 13].
