Abstract
An extraction method and an integrated cell for extracting a binary value based on a propagation of an edge of a triggering signal in two electric paths, including across two voltage supply terminals: two parallel branches each including, in series, a resistor for differentiating the electric paths; a read transistor, the junction point of the resistor and of the read transistor of each branch defining an output terminal of the cell, and the gate of the read transistor of each branch being connected to the output terminal of the other branch; and a selection transistor.
