Abstract
A delay circuit generates an output signal by delaying an input signal, and includes a ferroelectric capacitor having a first end and a second end, a means for inverting a polarization of the ferroelectric capacitor by producing an electric potential difference between the first end and the second end based on an electric potential of the input signal and a generation means for generating the output signal by delaying the input signal based on a change in an electric potential of the second end caused by the polarization inversion.
