Abstract
RF reader mainly consists of transponder and reader. Coding on the transponder based on AT89C2051 can be realized. Coded signals are modulated through resistance attached coupling LC circuit. Decoding and displaying can be completed using SCM on reader. Carrier signals at 125KHz produced by oscillator and frequency divider composed of CD4060 are emitted by a push-pull circuit consisted of transistor. The design has a novel thinking in the advantage of small volume, low cost, low power dissipation, high reliability and self-test function. © 2011 Springer-Verlag Berlin Heidelberg.
