The invention relates to an electric circuit for generating a periodic signal comprising: a capacitor device which has a first terminal and a second terminal; a signal node that is connected, via a first signal having a first period is applied; a discharging device that is connected, via a third switching device, to the first terminal and, via a fourth switching device, to the second terminal, whereby the second terminal, via a fifth switching device, and the first terminal, via a sixth switching device, are connected to a first reference potential; and comprising a clock pulse generating device for receiving the first signal and for generating a first switch clock pulse, a second switch clock pulse, and the periodic signal. The first and the second switch clock pulse do not overlap and are inverse with regard to one another. The first, third and fifth switch device can be controlled by the first switch clock pulse, and the second, fourth and sixth switch device can be controlled by the second switch clock pulse. The first and second switch clock pulse and the periodic signal have a second period, which is an even multiple of the first period.
