MUMBAI, India, Aug. 10 -- Intellectual Property India has published a patent application (202647089723 A) filed by Qualcomm Incorporated on July 23, 2026, for Low-Dropout (ldo) Regulator With Aggressor Current Cancellation.
Inventor includes Chao, Yue.
The application for the patent was published on July 31, 2026, under issue no. 31/2026.
Abstract: Techniques and apparatus for supplying power with aggressor current attenuation are provided. One example power supply circuit generally includes a low-dropout (LDO) regulator including an input coupled to a power supply node and an output coupled to a load circuit; a current replicator coupled to the output of the LDO regulator and configured to replicate a scaled version of an aggressor current to generate a fractional aggressor current; a current-steering circuit coupled to the current replicator and configured to replicate and reverse a polarity of the fractional aggressor current to generate a reversed fractional aggressor current; and a current mirror including an input coupled to the current-steering circuit and an output coupled to the power supply node, the current mirror being configured to sink an aggressor adjustment current from the power supply node based on the reversed fractional aggressor current.
