摘要： A mobile radio frequency identification (mRFID) reader having a receiving circuit is provided. The receiving circuit includes a local oscillator which generates a carrier signal at a predetermined frequency band; a mixer which mixes a tag signal received from a tag with the carrier signal, to lower a frequency of the tag signal; a phase adjusting block which adjusts a phase of the carrier signal by determining a phase of the tag signal; and a control block which processes the tag signal through a series of operations, and controls an operation of the phase adjusting block to compensate for a phase delay of the tag signal according to an output of the processed tag signal. Because the mRFID reader can be provided as small as a half size of a related art reader, a mobile communication terminal accommodating the mRFID reader can be compact-sized. Additionally, because the number of components for the receiving circuit decreases, not only the power consumption but also the unit price can be reduced.
摘要翻译：提供具有接收电路的移动射频识别（mRFID）读取器。所述接收电路包括以预定频带产生载波信号的本地振荡器; 混合器，其将从标签接收的标签信号与载波信号混合，以降低标签信号的频率; 相位调整块，通过确定标签信号的相位来调整载波信号的相位; 以及通过一系列操作来处理标签信号的控制块，并且控制相位调整块的操作，以根据处理的标签信号的输出来补偿标签信号的相位延迟。因为mRFID读取器可以被提供为相关技术读取器的一半的尺寸，所以容纳mRFID读取器的移动通信终端可以是紧凑型的。此外，由于接收电路的部件数量减少，所以不仅可以降低功耗，而且降低单价。
