MUMBAI, India, Jan. 3 -- Intellectual Property India has published a patent application (202511103608 A) filed by Indian Institute Of Information Technology, Allahabad, Uttar Pradesh, on Oct. 28, 2025, for 'digitally programmable variable gain amplifier using mosfets and mtjs for receiver systems and method thereof.'
Inventor(s) include Dr. Prasanna Kumar Misra; Apsana Khatoon; and Priyanka Tiwari.
The application for the patent was published on Dec. 12, under issue no. 50/2025.
According to the abstract released by the Intellectual Property India: "The present disclosure proposes a digitally programmable variable gain amplifier (VGA) (100) using Metal-Oxide-Semiconductor Field-Effect Transistors (MOSFETs) and Magnetic Tunnel Junctions (MTJs) that features dual programmability through digital Magnetic Tunnel Junction polarization states and analog control voltage tuning, low power consumption of 352.8 W, and precise gain adjustment from 6.69 to 9.37 decibels for efficient, robust low-Intermediate Frequency receiver applications. The VGA (100) supports a gain tuning range of 10.3 decibels in single-stage and 26 decibels in two-stage configurations. The VGA (100) bridges the performance gap. It combines low-power operation with flexible gain adjustment in receiver systems. The VGA (100) integrates with 40-nanometer CMOS technology. This ensures scalability for low-power applications."
