MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641043305 A) filed by Bapatla Surendra Babu; and Irukumalli Priyanka, Tenali, Andhra Pradesh, on April 4, for 'resonance-q harmonic-rejection switching-sustainer oscillator apparatus exploiting phase-controlled energy injection.'
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: "An apparatus reduces DC thermal dissipation in precision oscillators. Conventional linear amplifiers waste significant power as heat. The proposed solution replaces linear amplifiers with a switching-mode sustaining amplifier (120) governed by a phase-synchronization feedback loop (220). The loop enforces controlled energy injection within a defined phase window bounded relative to a zero-crossing of the resonant waveform. A high-quality-factor resonant element (110) utilizes its Q-dependent transfer function (310) to execute mechanical/electromagnetic harmonic filtering (320) of discrete switching pulses (210) possessing a discrete-time harmonic spectrum (230). This physical filtration yields an output oscillation (340) dominated by the fundamental resonant mode (750) with suppressed harmonic components (760), preventing amplitude-to-phase conversion (410). The apparatus achieves reduced DC thermal dissipation (430) without degrading spectral purity. It is principally used in 5G telecommunications and IoT devices to strictly comply with 3GPP network standards while extending operational battery lifespans."
