In most designs of circuits on master slices, NPN transistors have their collectors connected to the most positive voltage C++, their emitters to the least positive voltage EO, and their bases to a mid-range positive voltage B+. The structure of lateral NPN devices allows easy wiring even when a plurality of devices are connected in parallel. Fig. 1A shows lateral NPN devices having their bases connected together without requiring any underpasses.
