An electronic safety device circuit is disclosed. This circuit includes two integrated circuit operational amplifiers, the first connected as an operational amplifier and the second connected as a follower. The output pin of the first amplifier is connected to the positive input pin of the second amplifier through a diode. The positive input pin of the second amplifier is connected to a memory capacitor. The output pin of the second amplifier is connected to the negative input pin of the first amplifier. A switching network is provided for grounding the positive input pin of the first amplifier and discharging the memory capacitor.
