Then, on the basis of the functional verification, the system architectures of the radio frequency analog front end and the control logic circuit for the passive UHF RFID transponder are studied and designed with low-power design techniques. The RF AFE circuit includes rectifier, matching network, backscatter, regulator, AM demodulator, voltage reference, local oscillator and power on reset circuit, and so on. The control logic circuit contains clock synchronization module, decoding module, coding module, cyclic redundancy checksum module, power management unit, control unit, shift register and memory.

Because the encoding architecture doesn't need any shift registers and parallel to serial circuit, hardware resource is saved and the data throughput is improving.

由于該編碼器沒有使用移位寄存器以及并串轉(zhuǎn)換電路丁香五月激情黄色操一操，從而大幅度節(jié)約了硬件資源并提高了數(shù)據(jù)吞吐率。

The primitive polynomial of 3-12 pseudo-random sequence generator is obtained after the deductions. The better nonlinear feedback function of all states pseudo-random sequence generator can be picked out according to the characteristic of pseudo- random sequence signal, then using all states of shifting counter through modifying the linear shift register feedback network to realize the all states pseudo-random sequence signal.

Secondly, the properties of output sequences of stop-and-go clocked combiners are discussed. It is proved that the output sequences are stationary and obey strong law of large numbers and central limit theorem. Using the probabilistic model properly built, we analyze the rate of coincidence between the output sequences of two kinds of generators with basic operations and corresponding LFSRs sequences. All the computational formulae are derived. A recursive algorithm for efficiently computing the poster probability of partial input strings and corresponding joint probability is introduced. Moreover, divide-and-conquer attacks on this kind of generators which reconstruct the initial states of the input stop-and-go generators individually are proposed.
