Nvidia patents chip power trick to reduce electrical noise
Nvidia describes a circuit design for power regulators that cleans up electrical signals. It uses a sensor to detect changes in current and adjusts the signal to cancel out unwanted noise.
In the filing’s own words
A regulator for a load voltage includes a pass transistor for a load current, a gate voltage sensor coupled to a gate of the pass transistor, and a feed-forward supply noise cancellation circuit configured to amplify a gain of a supply noise cancelling signal at increments of the gate voltage.
What exactly they claim (claim 1)
1. A noise suppression circuit comprising: a pass transistor for a load current; and a feed-forward supply noise cancellation circuit configured to provide gain increments to generate a noise-cancelling signal at the gate of the pass transistor in response to changes in the load current.
