Abstract
An error detector and a method for detecting an error of an oscillator are provided. The error detector includes a receiver that receives an oscillation signal of an oscillator and a reference signal; and a controller that changes the oscillation signal within a frequency range so as to correspond to the reference signal and decides whether an error is generated in the oscillator based on the changed oscillation signal.
Claims23
An error detector comprising:
- a receiver that is configured to receive an oscillation signal of an oscillator and a reference signal;
- and
- a controller that is configured to change the oscillation signal within a frequency range so as to correspond to the reference signal and to decide whether an error is generated in the oscillator based on the changed oscillation signal.
A method for detecting an error of an oscillator, the method comprising:
- receiving an oscillation signal of the oscillator and a reference signal;
- changing the oscillation signal within a frequency range so as to correspond to the reference signal;
- and
- deciding whether the error is generated in the oscillator based on the changed oscillation signal.

A method for detecting a defect in an oscillator, the method comprising:
- receiving an oscillation signal from the oscillator and a reference signal;
- using a phase locked loop (PLL) to control the oscillation signal to try to lock the oscillation signal to the reference signal in a frequency range;
- and
- detecting a defect in the oscillator based on whether lock occurs in the frequency range.
