MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641043388 A) filed by Bapatla Surendra Babu; and Irukumalli Priyanka, Tenali, Andhra Pradesh, on April 5, for 'resonance-inertia pulsed-sustenance supply-decoupled oscillator apparatus exploiting duty-cycled isolation.'
Inventor(s) include Bapatla Surendra Babu; and Irukumalli Priyanka.
The application for the patent was published on April 17, under issue no. 16/2026.
According to the abstract released by the Intellectual Property India: "A supply-noise-immune oscillator apparatus executes power supply noise rejection utilizing intrinsic physical energy storage. A high-quality-factor resonant element (110) driven by a sustaining amplifier (120) possesses substantial stored energy (220). A switching element (140) intersects the DC power supply (130). The switch executes pulsed energy delivery (150) for a restricted duty cycle (160) (1%-50%), synchronized to intervals of minimal phase disturbance. For the remaining fraction of the cycle, the switch opens, enforcing coast-period supply disconnection (210). Direct electrical coupling pathways are eliminated, isolating active parameters from voltage transients (310). The continuous sinusoidal oscillation is maintained entirely by resonant inertia (230). This time-domain isolation reduces the effective pushing figure (330) proportionally to the duty cycle. The apparatus yields PSRR improvement (410), lowering phase noise contribution (420) from the supply and authorizing LDO elimination (430). It is principally used to protect precision timing modules in 5G and IoT networks from unregulated power supplies."
