Method and apparatus for on-die voltage fluctuation detection

An on-die device to determine voltage fluctuations, said devices to compare differential reference signals and monitored voltage signals at a first area of said die, wherein said device comprises:

• a control unit to provide said differential reference signals;
• and
• a first detector unit to receive said differential reference signals and to provide a first signal indicative of a differential voltage fluctuation at said first area,
• wherein said control unit comprises a voltage generator to receive a first reference voltage signal and a second reference signal from a source external to said die, said voltage generator to provide a control voltage reference signal, and
• wherein said control unit further comprises a programmable voltage-to-current converter to receive said control voltage reference signal and to provide said differential reference signal based at least on said control voltage reference signal.
