对于手持设备中常用的带电源迹线的配电网络(PDN)，基于集成电路(IC)开关电流激励的暂态电源电压纹波的严格闭合表达式，目标阻抗的概念可以得到显著改进。提出了建立目标阻抗的系统步骤，并将其应用于手持产品的PDN设计。对IC开关电流、PDN阻抗和电源纹波的测量表明，所提出的目标阻抗能够成功地将频域中的PDN阻抗与时域中的暂态电源电压纹波相关联。
The concept of target impedance can be significantly improved, based on the rigorous closed-form expressions for transient supply voltage ripple excited by an integrated circuit (IC) switching current, for the power distribution network (PDN) with power traces that is commonly used in handheld devices. A systematic procedure for developing the target impedance is formulated, which is then applied to the PDN design of a handheld product. From measurements of transient IC switching currents, PDN impedance, and supply voltage ripple, it is shown that the proposed target impedance successfully correlates the PDN impedance in the frequency domain with the transient supply voltage ripple in the time domain.
