Engineering Contradiction Analysis
1Loss of energy
If series-connected chips are used to maximize conversion efficiency, then power supply conversion efficiency is improved, but voltage levels and currents vary across stages leading to performance inconsistency
Solution Approach 1:
The patent changes the voltage parameter by introducing voltage conversion circuits between chip stages. These circuits convert voltages to consistent levels, ensuring that all chip stages operate at uniform voltage and current parameters, thereby resolving the performance inconsistency while maintaining the series connection's energy efficiency benefits
2Loss of energy
If multiple stages of series-connected chips are used, then power supply efficiency is improved, but wiring complexity and layout costs increase
Solution Approach 1:
The patent merges the ground ports of previous-stage chip domains with the primary power supply ports of next-stage chip domains. This consolidation reduces the number of separate connections needed, simplifying the wiring structure and reducing layout complexity while preserving the series connection power supply efficiency
