A method for adjusting delay time, and an integrated circuit chip comprising a first delay circuit trimmed via a second delay circuit are provided to adjust a second delay and a first delay on the basis of an oscillating signal, by trimming the first delay circuit. In an integrated circuit chip(24), a first delay circuit(28) has a first delay circuit topology configured to delay a signal by a first delay. A second delay circuit(30) has a second delay circuit topology configured to provide an oscillating signal and a second delay in a circuit loop configured to be monitored. The second delay circuit topology is actually equal to the first delay circuit topology, and the first delay circuit is configured to be trimmed in order to adjust the first delay on the basis of the second delay and the oscillating signal.
