Current Measurement for Power Converter Circuits - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240126353 titled 'Current Measurement for Power Converter Circuits
Simplified Explanation
The power converter circuit in a computer system includes a phase circuit and a sample circuit to adjust the voltage level of the regulated power supply node based on demand current and trigger events.
- The phase circuit compares the voltage level of the regulated power supply node to a reference voltage to generate a demand current.
- The demand current is used to adjust the voltage level of the regulated power supply node.
- The phase circuit digitizes the demand current and stores the resultant bit stream in a memory circuit.
- The sample circuit generates timestamp information that points to specific storage locations in the memory circuit corresponding to trigger events.
- This allows for analysis of the power converter circuit's operation under different circumstances and adjustment of operating parameters.

Unanswered Questions
How does the phase circuit precisely adjust the voltage level based on the demand current?
The exact mechanism by which the phase circuit adjusts the voltage level based on the demand current is not detailed in the abstract.
What specific trigger events are identified by the sample circuit for analysis of the power converter circuit's operation?
The abstract mentions trigger events, but does not specify what these events are or how they are determined.
Original Abstract Submitted
a power converter circuit included in a computer system may include a phase circuit and a sample circuit. the phase circuit compares a voltage level of the regulated power supply node to a reference voltage to generate a demand current that is used to adjust the voltage level of the regulated power supply node. the phase circuit also digitizes the demand current and stores the resultant bit stream in a memory circuit. the sample circuit generates timestamp information that points to particular storage locations in the memory circuit that correspond to trigger events, allowing the operation of the power converter circuit to be analyzed during different circumstances as well as to adjust operating parameters of the power converter circuit.
