2.7 Fast decay circuit
Very small fall time may be required in fast protocol, to be understood by the transponder in the field. This is
why, the EVB90109 include a “fast decay” circuit controlled through the pin FAST_DECAY and composed of
the transitstor Q1 and the diode D1. The following picture shows how to implement the “fast decay” system.
