Test structures consisting of embedded capacitors were fabricated using the FaradFlex capacitive internal layers. Impedance spectroscopy and equivalent circuit modelling was used to determine their electrical properties such as the capacitance, parasitic resistance and inductance. The use of several stages of...
SOFTOFF pin. It takes the driver only 456 ns after the turn-on (VEE+1.5V) of the driver stage to detect and react (VCC -1.5 V) to the short circuit event. A minimum short circuit time of 549 ns (according to [5]) is reached, showing the striking performance of the combination of...
eMMC(Embedded Multi Media Card)是嵌入式多媒体卡的简称,主要是针对只能手机和平板电脑特点二设计的。 它的实质是在NAND Flash的基础上增加了一个控制器,并预留了一个标准接口。 2、eMMC信号大体介绍 eMMC颗粒的PIN脚主要分为三组:电源引脚、控制信号引脚、数据信号引脚。 电源引脚 VCCQ电压:该电压由CPU的数据总线...
