Abstract:
A Digital power amplifier ( 13 ) to drive an RFID antenna ( 10 ) with a substantial sinusoidal output current (I) which digital power amplifier ( 13 ) comprises: an integrated circuit (IC 2 ) with a first transmission output pin ( 15 ) and a second transmission output pin ( 16 ) to provide an output signal ( 17 ); an adaption circuit ( 14 ) of discrete components (C 2 a,  C 2 b ) connected to the first and second transmission output pin ( 15, 16 ) to adapt the output signal ( 17 ) and feed the substantial sinusoidal output current (I) with a transmission resonance frequency to the RFID antenna ( 10 ), wherein the integrated circuit (IC 2 ) comprises: a digital control section ( 19 ) with a number of N wave-forming contacts ( 20 ) to output a digital wave-forming bit combination of N bits with a clock frequency M-times the transmission resonance frequency; a number of N driver blocks ( 21 ) each connected with a first contact ( 22 ) to one of the wave-forming contacts ( 20 ) and a number of N/2 of them connected with a second contact to the first transmission output pin ( 15 ) and the other number of N/2 of them connected with their second contact to the second transmission output pin ( 16 ), which driver blocks ( 21 ) are built to provide increments of the substantial sinusoidal output current (I) to the first and second transmission output pin ( 15, 16 ).

Claim (Index 1):
Digital power amplifier ( 13 ) that uses digital wave-forming bit combinations to drive an RFID antenna ( 10 ) with a substantial sinusoidal output current (I) which digital power amplifier ( 13 ) comprises:\n an integrated circuit (IC 2 ) with a first transmission output pin ( 15 ) and a second transmission output pin ( 16 ) to provide an output signal ( 17 ); an adaption circuit ( 14 ) of discrete components (C 2 a,  C 2 b ) connected to the first and second transmission output pin ( 15 ,  16 ) to adapt the output signal ( 17 ) and feed the substantial sinusoidal output current (I) with a transmission resonance frequency to the RFID antenna ( 10 ), characterized in that the integrated circuit (IC 2 ) comprises: a digital control section ( 19 ) with a number of N wave-forming contacts ( 20 ) to output a digital wave-forming bit combination of N bits with a clock frequency M-times the transmission resonance frequency; a number of N driver blocks ( 21 ) each connected with a first contact ( 22 ) only to one of the wave-forming contacts ( 20 ) and a number of N/2 of them connected with a second contact only to the first transmission output pin ( 15 ) and the other number of N/2 of them connected with their second contact only to the second transmission output pin ( 16 ), which driver blocks ( 21 ) are built to provide increments of the substantial sinusoidal output current (I) to the first and second transmission output pin ( 15 ,  16 ) and wherein each of the N/2 driver blocks ( 21 ) connected to the first transmission output pin ( 15 ) is built identical and each of the other N/2 driver blocks ( 21 ) connected to the second transmission output pin ( 16 ) is built identical.
