摘要： A compensation circuit provides a compensation current to a node of an integrated circuit that experiences increased reverse-bias leakage current between a n-type leaking epitaxial region and a p-type substrate with increased temperature. The compensation circuit includes a p-type substrate, a n-type compensator epitaxial region, an contact region, a center p-type region and a plurality of peripheral p-type regions. The peripheral p-type regions function as either a node collector or a reference collector. The compensation current is substantially determined by the ratio of the total peripheral surface area facing the center p-type region associated with the node collector and the total peripheral surface area facing the center p-type region associated with the reference collector and is also determined by the total surface area of the n-type compensator epitaxial region.
摘要翻译：补偿电路向集成电路的节点提供补偿电流，该集成电路的节点在具有升高的温度的n型泄漏外延区域和p型衬底之间经历增加的反向偏置漏电流。补偿电路包括p型衬底，n型补偿器外延区域，接触区域，中心p型区域和多个外围p型区域。外围p型区域用作节点收集器或参考收集器。补偿电流基本上由面对与节点收集器相关联的中心p型区域的总外围表面面积与面向与参考收集器相关联的中心p型区域的总外围表面积的比率确定，并且还由 n型补偿器外延区域的总表面积。
