摘　　要：为了降低集成在片上供电网络中的开关电容电压转换器的转换功耗和负载端的电压噪声,提出一种优化方案来优化开关电容电压转换器的转换电容和去耦电容两者间的电容资源分配。通过建立和求解不等式约束非线性规划问题,获得了转换电容和去耦电容共享电容资源的最优分配,有效地降低了电压转换器的转换功耗和电压噪声之和。实验结果表明,转换电容和去耦电容的组合优化方法能够将转换功耗和电压噪声之和降低约11%~28%。对于更大规模的供电网络,该优化方案能够有效地降低电压转换功耗和负载端的电压噪声。In order to reduce both the power loss of the switched capacitor converter integrated in the on-chip power delivery network and the voltage noise at the load,this paper proposes an optimization method to optimize the capacitance allocation between the flying capacitors of the switched-capacitor converter(SCCs)and the decoupling capacitors at the load.By formulating and solving the inequality-constrained nonlinear programming problem,the SCCs’flying capacitance and decoupling capacitance can be optimally allocated and the sum of power loss and voltage noise is effectively reduced.Experimental results show that the joint optimization of the SCCs’capacitance and decoupling capacitance can reduce the sum of power loss and voltage noise by about 11%~28%.For larger power deliver networks,this method can efficiently reduce the power loss and voltage noise.
