Method and circuit arrangement for determining power supply noise
摘要:
The present invention relates to a method and circuit arrangement for determining power supply noise of a power distribution network. The power supply noise is determined by measuring the propagation delay of a delay circuit powered by the power distribution network, wherein the result of the measuring step is used as an indicator of the power supply noise. Thereby, a real-time power supply noise monitoring can be carried out at any point of a power distribution network of an observed circuitry.
