An integrator and a circuit-breaker are disclosed, the integrator being in the form of a passive symmetrical low-pass filter having an integration capacitor. In order to make it possible to temporally integrate an electrical signal in an improved manner, it is proposed in at least one embodiment that provision be made of a differential amplifier having two amplifying elements each having an input, that the two amplifying elements be coupled to one another in order to generate a differential signal, that the inputs of the two amplifying elements be connected to one another via the integration capacitor, and that each amplifying element be positively fed back to its input via a feedback loop in such a manner that the two amplifying elements together form a negative input resistance in parallel with the integration capacitor. |
