| 摘 要： | 提出了在Zigbee标准的RFID系统中有源标签电源处采用LDO稳压器,以减少电流损耗。进行了有无LDO模块的两组对比实验,对有源标签消耗电流进行了测量。结果表明,当采用LDO调整输入电压时,电流损耗仍保持稳定,且系统射程有所增加。

| Abstract: | This paper studied using low-dropout(LDO) voltage regulator in order to reduce current consumption in the active tag RFID system using the ZigBee standard.Label non-beacon data transfer mode.Two sets of tests were conducted using tags with and without LDO voltage regulators,separately.We determined the current consumed by the active tag,and the results showed that,when LDO regulator voltage was used to adjust the input voltage,the current consumption remained stable,and the system transmission range was increased. |
