Increasing of Operation Range of RFID System
Igor B. Shirokov · 2019
The problems of RFID system operation are discussed. One way of energy increasing of RFID link is suggested. Mentioned issue can be achieved by the use of one-port reflection transistor amplifier in transponder design. The simulation, design, and operation of one-port resonant transistor amplifier are considered. Amplifier consists of single FET and resonant circuit. The operation of amplifier is based on the use of positive feedback. This is the class of regenerative amplifiers. Amplifier possesses excellent electrical characteristics and has a simplest design. Discussed amplifier will be especially useful at design of active transponder of RFID system.
