Abstract
A system for on-die voltage difference measurement on a pass device comprises a first voltage controlled oscillator circuit having a first voltage control input connectable to a first terminal of the pass device; a second voltage controlled oscillator circuit having a second voltage control input connectable to a second terminal of the pass device; a first counter circuit arranged to count oscillation periods of a first output signal from the first voltage controlled oscillator circuit and to provide a stop signal when a predefined number of the oscillation periods of the first output signal is counted; and a second counter circuit arranged to count oscillation periods of a second output signal from the second voltage controlled oscillator circuit and to stop counting depending on the stop signal.
