Abstract
A protection circuit against the electrostatic discharges that could appear at the terminals of a circuit, wherein said protection circuit comprises a first transistor made in a well whose potential is a floating potential and enabling the value of the discharge voltage to be limited to a value equal to minus the value of the threshold voltage of said first transistor and a second transistor made in a well whose potential is a floating potential and enabling the value of the discharge voltage to be limited to a value equal to the value of the threshold voltage of said second transistor. The disclosure can be applied to MOS technology integrated circuits.
