Abstract
Voltage drop introduced by long cable cannot be neglected any more in high-power remote-loading applications, e.g., power adaptor for the charger of modern smart phones or tablets. In this paper, self-adaptive wire drop compensation (WDC) schemes for DC-DC regulator have been proposed and discussed. A 3.5-A buck DC-DC regulator with the proposed WDC circuit has been implemented in 0.6μm CMOS technology. Simulation results show that the load regulation (0.004 V/A) is typically improved by 51 times than the circuit without WDC when load current changes from 0.5 A to 3 A.
