| description | A power Darlington array layout structure is designed based on the 70 V high voltage bipolar process. The structure is suitable for the output stage layout of the single-chip high-voltage power device. It consists of symmetric interdigitated array unit structure, and has the characteristics of large current driving capability, uniform heat dissipation, good stability, and high area utilization. The interdigitated-emitter and interdigitated base ensure a high speed while taking into account the matching and symmetry of the array power transistor. The two-sided design of the interdigitated base increases the effective emitter perimeter and improves current conduction capability. The improved equi-plane wiring reduces the wiring steps and makes the high current layout possible. Simulation based on calibre proves the layout has the ability to output current of 9 A. |
