Abstract
A device may include an oscillator circuit, a control circuit, a frequency detector circuit, and a processor circuit. The oscillator circuit may include a frequency control input to output an oscillator signal. The frequency of the oscillator signal depends on an input signal applied to the frequency control input. The control circuit is configured to apply a first input signal value, a second input signal value, and a third input signal value to the frequency control input. The frequency detector circuit is configured to detect the first frequency value of the oscillator signal when the first input signal value is applied to the frequency control input, a second frequency value of the oscillator signal when the second input signal value is applied to the frequency control input, and a third frequency value of the oscillator signal when the third input signal value is applied to the frequency control input.
