Abstract
a circuit for an RFID device in one embodiment includes an operational amplifier having a first input, a second input, and an output where the first input receives an incoming signal, arid the second input is coupled to the output via a feedback loop. An operational amplifier for an RFID device according to another embodiment compares an output of the operational amplifier to an incoming baseband signal, A circuit according to another embodiment includes an operational amplifier having a first input, a second input, and an output, wherein the first input receives an incoming signal, and wherein the second input is coupled to the output via a feedback loop. A comparator having one input is coupled to the output of the operational amplifier, another input receiving the incoming signal, and an output for outputting an outgoing signal. Methods for adjusting a filtering characteristic of an operational amplifier are also disclosed.
