MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641043166 A) filed by Bapatla Surendra Babu; and Irukumalli Priyanka, Tenali, Andhra Pradesh, on April 4, for 'parametric phase-noise cancellation apparatus exploiting amplitude control signals for quality factor jitter compensation.'
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 parametric phase-noise cancellation apparatus executing active phase noise suppression. A resonant element (110) driven by a sustaining amplifier (120) generates a raw oscillator output (330). Two-level system defects (210) cause quality factor jitter (220), executing parametric modulation (230) of a Leeson thermal noise floor (240), generating dominant flicker-of-frequency phase noise (250). An automatic gain control loop (130) generates an AGC correction signal (140) proportional to the quality factor jitter. A parametric noise predictor (150) extracts this signal to compute a predicted parametric phase noise signal (310). A correlation subtraction processor (320) electronically subtracts this prediction from the raw output. Bounded by an AGC-phase correlation coefficient (340), the system yields a purified oscillator output (410) demonstrating phase noise suppression (420) relative to a static-Q Leeson prediction (430), achieving equivalent Q enhancement (440) utilizing zero additional hardware."
