A device includes an oscillator including at least one inductor and at least one capacitor and configured to generate, based on a positive supply voltage, an output signal oscillating in a resonance frequency of the at least one inductor and the at least one capacitor. The device further includes an oscillation detector configured to determine whether the output signal oscillates based on a clock signal and increase a loop gain of the oscillator until the output signal oscillates.

Device and method for adaptive loop gain of oscillator

A monitoring circuit for a high frequency signal includes: a phase locked loop configured to generate a divided output signal with respect to an input signal based on a plurality of dividers; a plurality of dividing monitoring circuits configured to receive dividing input signals and dividing output signals respectively corresponding to the plurality of dividers, and output dividing error signals; and a jitter monitoring circuit configured to output a jitter error signal.

Monitoring circuit of phase locked loop and operating method thereof

A temperature compensated oscillation controller includes a temperature compensation circuit configured to provide a reference voltage through a first terminal and to receive an input voltage including temperature information through a second terminal, and an oscillation circuit configured to be connected to an external crystal resonator through third and fourth terminals and to output a clock signal in response to an oscillation signal from the external crystal resonator. The temperature compensation circuit is configured to perform a voltage controlled oscillator-based sensing operation to convert the input voltage into a temperature code and to adjust a frequency of the clock signal using the temperature code.
