MUMBAI, India, April 17 -- Intellectual Property India has published a patent application (202641043165 A) filed by Bapatla Surendra Babu; and Irukumalli Priyanka, Tenali, Andhra Pradesh, on April 4, for 'self-thermometry oscillator apparatus exploiting amplitude-frequency nonlinearity for dynamic frequency stabilization.'
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: "Electronic oscillators suffer frequency drift due to temperature changes, conventionally requiring external thermistors that introduce thermal lag errors. A self-temperature-compensating oscillator apparatus utilizes endogenous material nonlinearity to derive temperature without external sensors. A pilot-tone generator (130) injects amplitude modulation (140) into a resonant element (110). A pilot-tone response detector (310) extracts a frequency modulation response (330) proportional to a temperature-dependent isochronism coefficient (220). A temperature extraction processor (340) utilizes this independent thermometric channel (230) to calculate the temperature of the resonating mass (350), substantially eliminating thermal lag (360). A frequency compensation processor (430) applies a correction based on a temperature coefficient of frequency (210), outputting a stabilized output signal (440). This achieves residual drift minimization (450) for 5G and aerospace precision timing applications without component modifications."
