  • Oscilloscope noise floor de-embedding for high speed toggle signal measurement
    Patent number: 11614468
    Abstract: A scheme for noise floor de-embedding by identifying a link or relationship between noise floor from an oscilloscope and phase jitter impact on a toggling signal. The scheme uses phase or electrical spectrum and phase detection for noise floor recognition. The scheme de-embeds the impact from random noise and also removes deterministic noise or jitter from the oscilloscope. The scheme provides accurate jitter analysis for a circuit (e.g., clock data recovery circuit) after de-embedding noise floor for the oscilloscope.
