A current-to-voltage detection circuit includes a detection circuit, a reference voltage component, a resistor component, a load, a detection part, and an amplifier, wherein the detection circuit uses the reference voltage component to produce a fixed reference voltage which come up with a reference potential at a point B. When the load is turned on to form a system loop, a grounding end of the detection part can produce a reference potential of tiny mV at a point A; whereas a common reference potential is produced at a point C upon comparing the point A with the point B. When the reference potential at the point A is greater than the reference potential at the point B, a voltage at the output end of amplifier is converted from a low potential into a high potential, and a circuit of related system can be controlled by a change between the potentials.
