Would it be better to use a full wave bridge rectfier instead, a single diode will only give a half rectified voltage, or does it not really matter?rautio said:Next connect a small signal diode in series with a parallel RC circuit
At the moment, it is unclear what the impedance of the RFID tag chip will be, are they usually 50 ohms?rautio said:Select the RC according to the input impedance of the RFID tag chip you plan to use
rautio said:For measuring the voltage, one diode will be plenty. If you actually want to get some power out of the circuit (like the RFID chip does), two diodes would be a good idea.
rautio said:If you do not know what the input impedance is, just make sure you have a high value of resistance and make sure the time constant is much longer than 1/f.
