Summary:The invention relates to the provision of an on-chip capacitor resulting in improved testability and reliability of the entire chip. The on-chip capacitor according to the invention is realized by a complementary cross-coupled structure which has a flip-flop characteristic. If a leakage current occurs in one of the transistors of the entire circuit structure this will cause the structure to switch into another state so that the leakage current is cut off. Thereby the on-chip capacitor is self-repairing as regards pinholes which develop over time. Condensateur incorporé à une puce, améliorant la capacité de se prêter aux essais ainsi que la fiabilité de toute la puce. Le condensateur intégré à la puce selon l'invention est réalisé au moyen d'une structure interconnectée complémentaire possédant une caractéristique de bascule. Si un courant de fuite se produit dans l'un des transistors de la structure de circuits, la structure bascule sur un autre état de façon à interrompre le courant de fuite. Ainsi, le condensateur incorporé à la puce répare lui-même les trous qui apparaissent avec le temps.
