Abstract: A detection stage of an electronic detection device, for example a pH meter, includes an insulating region that receives an element to be analyzed. The insulating region is positioned on a sensing conductive region. A biasing stage includes an electrically conductive region which is capacitively coupled to the conductive region. The electrically conductive region is formed in an uppermost metallization level along with a further conductive region. That further conductive region is electrically connected to the sensing conductive region by a via passing through an insulating layer which insulates the electrically conductive region from the sensing conductive region.
