Abstract
Circuit nodes are identified which, in unpowered mode, can be charged with positive or negative charges but cannot be discharged. Then protective elements are added to allow the discharge of these nodes. These elements do not affect the operation of the circuit in powered mode. Discharges of the two polarities are handled, positive and negative. The circuit is thus more resistant to ESD and passes CDM tests.
