Abstract
A linear, bipolar-type application-specific integrated circuit includes a silicon substrate having a plurality of columns of device primitives or cells. Each cell comprises a plurality of identical NPN and PNP transistors flanking a centrally-located capacitor. Each transistor has dual emitters, bases and collectors. Open field areas are reserved on the silicon substrate on the sides of the columns of cells. Formed in these open field areas are precise thin film silicon chromium resistors. Power planes are also routed in these open field areas. A ground plane is routed in the vicinity of the centrally-located capacitor. Standard analog circuits are personalized using two layers of metallization interconnects.
