1. An apparatus, comprising:
voltage monitoring circuitry for sensing voltage changes and having a first connection point and a second connection point; and
a pair of leads connected to a die at points internal to the die such that the pair of leads is connected across a load at a point of load, and coupled to the first connection point and the second connection point to enable the voltage monitoring circuitry to sense a differential voltage associated with an effective power supply voltage at the point of load, wherein the differential voltage comprises a voltage change having a duration less than 100 nanoseconds, and wherein the duration is a continuous period of time that the differential voltage is below a lower threshold voltage, or a continuous period of time that the differential voltage is above an upper threshold voltage.
