MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202541036570 A) filed by International Institute Of Information Technology, Hyderabad, Telangana, on April 15, 2025, for 'voltage-controlled oscillator circuit that reduces phase noise at a millimeter-wave signal.'
Inventor(s) include Abhishek Srivastava; Narahari N. Moudhgalya; and Adarsh Yadav.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "An embodiment herein provides voltage-controlled oscillator (VCO) circuits for reducing phase noise (PN) at millimeter-wave (mmWave) signals with harmonic shaping and noise circulation. The embodiment includes (i) a triple-coupled stacked transformer (XFMR)-based VCO and (ii) a MEMS-based VCO, each configured with distinct architectures. The XFMR-based VCO comprises a resonator with magnetically coupled inductors, stacked metal layers, patterned ground shield, switched capacitor array, common-mode capacitors, and differential-mode capacitors, along with transistor pairs cross-coupled using XFMR to generate negative resistance and enable harmonic shaping. The MEMS-based VCO employs a micro-electromechanical resonator for high-Q operation and reduced phase noise. Both VCO configurations independently enhance phase-noise performance while maintaining stable oscillation at mmWave frequencies."
