This means that we can analyze the circuit as if they aren’t even there, and when we do that, we see that the limiter is just a typical inverting op-amp with some resistors connected between the output and the supply voltages.

WebAs shown in Figure 1, low-side current sensing connects the sensing resistor between the load and ground. Normally, the sensed voltage signal (VSEN=ISEN × RSEN) is so small that it needs to be amplified by subsequent op amp circuits (e.g., non- inverting amplifier) to get the measurable output voltage (VOUT).
