Abstract
A delay circuit includes a delay device, to which an input signal is supplied. A first phase-shifted signal can be generated by the delay device, which is delayed by a first delay time with respect to the input signal, and a second phase-shifted signal can be generated, which is delayed by a second delay time with respect to the input signal. The delay device is configured such that the first and second phase-shifted signal can be generated in inverted fashion with respect to one another at an output terminal of the delay device after a delay of the input signal by a delay time.
