A SIMPLE AND STABLE REFERENCE FOR IR-DROP AND SUPPLY NOISE MEASUREMENTS

摘要

Apparatus and method for IR-drop and supply noise measurements in electronic circuits. A first voltage at a point of interest in the circuit is sampled and stored during a quiescent mode of the circuit the voltage is to be measured in. Subsequently, the circuit is brought in an operating mode and a second voltage is sampled and held at the same point of interest. The first and the second voltage are compared and a corresponding voltage signal is passed to a system output.
