Circuit (1) comprising: - a first (E1) and a second (E2) input terminal, - a first comparator (10) having a first input at an electrical potential depending at least in part on the electrical potential of the first input terminal (E1), said first input being compared with the electrical potential of a second input of the comparator so as to determine the state of the first comparator, - a second comparator (20) having a first input at an electrical potential depending at least in part on the electrical potential of the second input terminal (E2), said first input being compared with the electrical potential of a second input of the comparator so as to determine the state of the second comparator.
