ElectricPCB: Creating a RFID Reader From Scratch Part 2
The transmitter is a simple current amplifier, where the transistors Q1 and Q3 will alternately pull the antenna voltage high and low depending on the "control" signal in to the amplifier, thus forcing a high current through the antenna. The important thing to note is that this circuit does not generate any frequency signal on itself, it requires a source that produces the correct frequency, the...
