MUMBAI, India, July 13 -- Intellectual Property India has published a patent application (202617075779 A) filed by Telefonaktiebolaget Lm Ericsson Publ on June 18, 2026, for A Procedure To Operate High Frequency Crystal Oscillators.
Inventors include Abdulaziz, Mohammed; and Elgaard, Christian.
The application for the patent was published on July 10, 2026, under issue no. 28/2026.
Abstract: Methods and circuits for detecting and controlling for parasitic oscillations in a crystal oscillator circuit. An example method comprises initializing (710) power-up of the crystal oscillator circuit, wherein said initializing (710) power-up comprises increasing an effective transconductance of the crystal oscillator circuitry over time, at a first rate, and detecting (720) a frequency of oscillation of the crystal oscillator circuit. This example method further comprises, in response to determining that the detected frequency of oscillation is lower than a target frequency, restarting (730) power-up of the crystal oscillator, wherein said restarting power-up comprises increasing the effective transconductance of the crystal oscillator circuitry over time at a second rate that is slower than the first rate.
