Beschreibung
Zusammenfassung:	The invention relates to a device for diagnosing an antenna (L) of a resonator circuit combined with an amplifier comprising a first transistor (HS1) and a second connected transistor (LS1), and an amplifier output (OUT1). The first transistor (HS1) and the second transistor (LS1) are symmetrically mounted and the amplifier output (OUT1) is arranged between the two transistors. The device comprises: a means for measuring a current flowing in a connection of each of said transistors; a first means for generating an input signal, which is connected to the first transistor; a second means for generating an input signal, which is connected to the second transistor; and an electronic means (8) having an output providing an output signal representative of the potential (V_OUT1) at the amplifier output. The invention also relates to a method for diagnosing an antenna using such a device.
