Abstract

In RF application the power management and charging of batteries for wireless low power devices is a big issue. In this paper we are presenting the efficient energy at input output section of RF application. Analysis of input impedance using three matching topology is necessary to get maximum power transformation which is then converted into DC signal. The voltage level of incoming input signal is 359.26mV which is further passes through Step-Up transformer which increases the voltage level upto 3.659V. Here we used, MOSFET in spite of diode in voltage multiplier because it gives an linear output compare to diode and noise free DC signal output. We observed that at 0dBm input power, output DC voltage is greater than the output DC voltage at -5dBm which gives an output of 1.778V and at -10dBm which gives an output of 1V. It gives an pure output DC voltage of 3.162V at 0dBm input power and stored the energy of 3.79〖×10〗^(-10) J while it is dissipated the power of 0.189W at 2ns time period. And it gives an voltage efficiency of 86.18% at 50Ω load. It can develop sufficient voltage for driving low power electronic devices.
