Patent number: 12164319Abstract: A dual-loop low-drop (LDO) regulator having a first loop which is an analog loop that compares the voltage on the output supply node with a reference, and generates a bias or voltage control to control a strength of a final power switch. The first loop regulates the output voltage relative to a reference voltage by minimizing the error between the two voltages. A second loop (digital loop) that controls a current source which injects current on the gate of the final power switch to boost current for a load. The second loop is an auxiliary loop that boosts the current load for a set interval until the tracking bandwidth of the LDO resolves the error in the output, thereby reducing the peak-to-peak noise. The quiescent current is not increased a lot by the second loop since the second loop circuit is on for a fraction of the entire LDO operation.Type: GrantFiled: December 19, 2020Date of Patent: December 10, 2024Assignee: Intel CorporationInventors: Sathya Narasimman Tiagaraj, Gerald Pasdast, Edward Burton

Publication number: 20240329129Abstract: Technologies for a unified debug and test architecture in chiplets is disclosed. In an illustrative embodiment, several chiplets are integrated on an integrated circuit package. The chiplets are connected by a package interconnect, such as a universal chiplet interconnect express (UCIe) interconnect. Each chiplet includes several debug nodes, which are connected by an on-chiplet network. One of the chiplets, referred to as a package debug endpoint, acts as a link endpoint for an off-package link, such as a peripheral component interconnect express (PCIe) link. In use, debug messages can be sent to the package debug endpoint over a PCIe link. The debug messages can be routed within the chiplets and between chiplets, allowing for the debug functionality at each debug node to be probed using a common protocol. In this manner, chiplets from different vendors can be integrated into the same package and tested using common software.Type: ApplicationFiled: December 12, 2023Publication date: October 3, 2024Applicant: Intel CorporationInventors: Sridhar Muthrasanallur, Debendra Das Sharma, Swadesh Choudhary, Gerald Pasdast, Peter Onufryk

Publication number: 20240183884Abstract: Embodiments herein relate to a chiplet or other die which includes multiple sense points within the die and components for digitizing and outputting sensed voltages of the sense points. In one approach, an analog-to-digital converter (ADC) is coupled to each sense point, and a multiplexer is coupled to the outputs of the ADCs. A select signal for the multiplexer can be received from an external control unit which selects one of the sense points based on information such as a current workflow of the die. The selected sense point can change as the workflow changes. The optimal sense point can be determined by comparing the voltage of each sense point and selecting the sense point with the lowest voltage. The sensed voltage is provided to a voltage regulator as a feedback signal to optimize control of the power supply of the die.Type: ApplicationFiled: December 6, 2022Publication date: June 6, 2024Inventors: Vikrant Thigle, Vijay Anand Mathiyalagan, Anand Haridass, Arun Chandrasekhar, Gerald Pasdast
