MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541122980 A) filed by Vellore Institute Of Technology, Vellore, Tamil Nadu, on Dec. 5, 2025, for 'low power vco topologies with enhanced fom for rf systems in 45nm technology.'
Inventor(s) include Dr. Abdul Majeed K K; and K Raj Kumar.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "The present disclosure provides a VCO System Architecture (400) implemented in 45nm CMOS technology. The VCO System Architecture (400) includes a 45nm CMOS Technology Platform (402) and a VCO Architecture Selection (408) encompassing three distinct oscillator topologies: a Delay Cell VCO (410) with Ring Oscillator (412) and Current Starved Stages (414), an LC-VCO (416) with Resonant Tank (418) and Cross-Coupled Pair (420), and a Quadrature VCO (422) with Dual LC Tanks (424) and Coupling Network (426). The architecture includes a Performance Analysis System (428) with Frequency Characterization (430), Phase Noise Analysis (432), and Power Consumption (434) modules, and an Application Integration (436) component with PLL Systems (438), RF Transceivers (440), and Digital Clocking (442) applications."
