Rfid transponder and operating the same


An rfid transponder having an analog front end receiver having an attenuator coupled to receive an rf-signal from an antenna and to attenuate the rf-signal, an amplifier having a fixed amplifier gain and being coupled to receive and to amplify the attenuated rf-signal and a control unit coupled to control a gain of the attenuator, wherein the control unit is configured to control the attenuator gain in response to a level of the amplified rf-signal, the control unit is configured to have a plurality of predetermined states causing the attenuator to increase (step-up) or to decrease (step-down), its gain by a predefined step size, wherein the step size of a step-up is equal to or smaller than the step size of a step-down and wherein the control unit is further configured to switch, upon reaching or exceeding a predefined threshold value, from a first to a second state having a smaller step size and causing the attenuator to change the gain such that the slope of the rf signal inverts and to switch, upon reaching the predefined threshold again, to a third state causing the attenuator to change a prefix of the gain.. .
