Abstract
Embodiments of the present invention are described in an integrated circuit. The integrated circuit comprises circuit elements configured to be clocked via an oscillating signal, and a detector. The detector is configured to detect a state of the oscillating signal and provide a detection signal indicative of the state of the oscillating signal. The detector comprises a first delay line configured to provide a first delayed signal to logic that provides the detection signal.

An integrated circuit, comprising:
- circuit elements configured to be clocked via an oscillating signal;
- and
- a detector configured to detect a state of the oscillating signal and provide a detection signal indicative of the state of the oscillating signal, wherein the detector comprises a first delay line configured to provide a first delayed signal to logic that provides the detection signal.
An integrated circuit, comprising:
- a circuit element configured to be clocked by a first oscillating signal;
- and
- a first detector configured to detect a state of a second oscillating signal and provide a first detection signal indicating the state of the second oscillating signal, wherein the first detector is configured to sample the second oscillating signal at a sampling rate derived from the first oscillating signal.
A method for detecting a state of an oscillating signal, comprising:
- providing the oscillating signal to a first delay line;
- obtaining a first delayed signal from the first delay line;
- and
- providing the first delayed signal to detection logic.
