ePrint Reportpower consumption requirements in passive RFID systems. Warbler is built upon three nonlinear feedback shift registers (NLFSRs) and four WG-5 transformation modules. We employ two design options to implement Warbler and three different compilation methods to further optimize the area, maximum operating frequency, and power consumption. We can achieve an area of 498 GEs after the place and route phase in a CMOS 65nm ASIC, with a maximum frequency of 1430 MHz and a total power consumption of 1.239 uW at 100 KHz. Accordingly, an area of 534 GEs after the place and route phase, with a maximum frequency of 250 MHz and a total power consumption of 0.296 uW at 100 KHz can be obtained in a CMOS 130nm ASIC. Our results show that the LFSR counter based
design is better than the binary counter-based one in terms of area and power consumption. In addition, we show that the areas of WG-5 transformation look-up tables depend on the specific decimation values.
