Abstract
An on-chip voltage sensor that selectively eliminates noise from a voltage measurement is provided. The on-chip voltage sensor has resistive and capacitive components in the voltage divider, thus allowing a voltage on a section of a computer chip to be measured exclusive of high-frequency noise. Further, a method for measuring a voltage on a section of a computer chip using a voltage divider having a resistor and a capacitor is provided. Further, a computer chip having an on-chip voltage sensor is provided. Further, a method and apparatus for observing voltages at multiple locations on an integrated circuit.
