    2013Published online: 8 February 2013 Abstract In order to reduce the power consumption of RFID tags and increase the reading range of RFID systems‚ this paper proposes an ASK demodulator that uses a new approach to reduce the threshold voltage of diode connected MOS transistors as an obstacle in the design of the envelope detector. Also‚ an ultra low power comparator is used for further power reduction. This circuit has been simulated in a 0.18 μm CMOS technology to satisfy EPC Class 1 Generation

    Was the existing system adequate in the past? Why or why not? Why is it no longer adequate? The existing system was adequate in the past due to heavy reliance on direct labor hours. The ETO served as a central cost center‚ and transferred the costs to other divisions at direct costs plus allocated burden. Being in the late 1970s and early 1980s‚ technology testing of components required fewer cycles‚ and less complicated structures. Hence‚ such testing on products could be carried out by direct

    is rated at only 100 Vdc). FIGURE 3 From Figure 3: A diode in series with a resistor is connected across the inductor to resolve the arcing phenomena across the switch. At t 0‚ when the switch is opened‚ the diode is forward bias hence allowing current to its branch. The current‚ I in this circuit is then given by: (VL - VF ) /R ‚ where VF is the forward voltage drop of the diode. The stored energy in the inductor is dissipated as heat in the resistor. Consequently
