Based on information from Tianyancha, Shanghai Primarius Technologies Co., Ltd. has been granted an invention patent titled "Parameterized Configurable Automatic Generation Method and Device for Digital LDO," with the authorization announcement number CN119272694B. The patent was officially authorized on October 14, 2025, following an application submitted on September 24, 2024.

This patent specifically targets the challenges of lengthy development cycles and high costs that arise from repetitive simulation verifications and multiple schematic/layout revisions in the conventional design process for digital low-dropout linear regulators (LDOs). The innovation lies in its approach: by configuring variable design parameters within the digital LDO circuit and establishing a direct correlation between configurable performance parameters and circuit design parameters, users can effortlessly generate the corresponding digital LDO netlist files and layout files. This is achieved simply by inputting the desired performance parameters. As a result, the method drastically cuts down on circuit design time, facilitates agile design practices, and significantly boosts both design efficiency and flexibility.
