摘要： Provided is a demodulator circuit allowing a tag or transponder to efficiently recover data of an input amplitude signal at very low power in a wireless communication system such as a radio frequency identification (RFID) system. The demodulator connects an output of a voltage multiplier to a low-current path by capacitive coupling, thereby recovering data. Therefore, data is recovered, at low power, from an input amplitude signal having a low modulation depth, and it is possible to increase a communication distance.

摘要： A terminal supporting peer-to-peer (P2P) communication, wherein a transceiver of the terminal is implemented to support P2P communication with an adjacent terminal in the same cell. Thus, when short-range communication is possible, the terminal performs P2P communication directly with the adjacent terminal, not via a base station. Consequently, when terminals use different mobile telecommunication service providers or there is no base station network, the terminals can be used for short-range communication. More particularly, when a receiving channel state becomes satisfactory while communication with an adjacent terminal is being performed via a base station, the terminal directly switches to a P2P communication mode and performs communication with the adjacent terminal. On the contrary, when the receiving channel state deteriorates while communication with the adjacent terminal is being performed in the P2P communication mode, the terminal directly switches to a base station communication mode and performs communication with the adjacent terminal.
摘要翻译：一种支持对等（P2P）通信的终端，其中终端的收发机被实现为支持与同一小区中的相邻终端的P2P通信。因此，当短距离通信成为可能时，终端不直接通过基站直接与相邻终端进行P2P通信。因此，当终端使用不同的移动电信服务提供商或者没有基站网络时，终端可以用于短距离通信。更具体地，当通过基站进行与相邻终端的通信时，当接收信道状态变得令人满意时，终端直接切换到P2P通信模式并与相邻终端进行通信。相反，当在P2P通信模式中正在执行与相邻终端的通信时，当接收信道状态恶化时，终端直接切换到基站通信模式并与相邻终端进行通信。

摘要： Provided are an image sensor and a method of sensing the same. The image sensor includes: a light receiving device; a signal conversion unit including a transfer transistor having a plurality of transfer gates and for converting photocharges generated by the light receiving device into a voltage to output the voltage; and a sensing control unit for generating at least two reset signals and/or at least two transfer signals applied to the transfer gates of the transfer transistor during a one-time photosensing cycle. The image sensor is obtained by changing the structure and driving method of a transfer transistor of a typical 4-transistor CMOS image sensor and employs a deep depletion operation and a multiple reset operation, thereby reducing an image lag and increasing the well capacity of the light receiving device.
