Abstract: An integrated circuit, IC, comprising one or more DC blocking modules connected to a respective input/output, IO, pin of the IC, each DC blocking module comprising: a capacitor having a first terminal connected to the respective IO pin and a second terminal connected to a node of the circuitry of the IC; and an electrostatic discharge, ESD, protection circuit connected in parallel to the capacitor, the ESD protection circuit comprising: a conduction path connected between the first terminal of the capacitor and the second terminal of the capacitor; and a control terminal configured to receive a control signal to switch the ESD protection circuit between: an operational mode in which the conduction path is in a non-conducting state and provides ESD protection to the capacitor; and a test mode in which the conduction path is in a conducting state and short circuits the capacitor.
