Voltage-drop measuring circuit, semiconductor device and system having the same, and associated methods |
摘要 |
A voltage-drop measuring circuit is capable of measuring a voltage-drop of a power supply voltage caused by a resistance component of a power line. The voltage-drop measuring circuit includes a sensing circuit and a voltage-drop detecting circuit. The sensing circuit includes a sensor configured to generate a sensing voltage received by the sensor from a power pad through a power line between the sensor and the power pad. The voltage-drop detecting circuit is arranged in a neighborhood of a power pad, and is configured to generate a reference voltage, compare the sensing voltage with the reference voltage to detect the voltage-drop, and generate a detecting signal in accordance with the voltage-drop.
