Predrivers

The predrivers generate the signals for the four power transistors of the full bridge using the carrier frequency generated by the frequency divider. The gate signals of the P-channel power transistors (active low) have the same width (±1 cycle of the 16 MHz clock), the delay between one P-channel MOSFET being switched off and the other one being switched on is defined to be 12 cycles of the 16-MHz clock. In write mode the first activation of a gate signal after a bit pause is synchronized to the received transponder signal by a phase shift of 180°.
