AN912 Designing LF Talkback

AN912 Designing LF Talkback for a Magnetic Base Station Author: Ruan Lourens Microchip Technology Inc. MAIN BUILDING BLOCKS Figure 1 shows the main building blocks that make up the LF Talkback system described in this document. The base station generates a strong magnetic field by setting up resonance in a serial resonant tank. The circulating energy in the resonant tank typically generates 300V peak-to-peak voltage across the transmitting antenna coil at 125 kHz. The transponder, whether activ.
