ABSTRACT:
Provided are a method, system, and device directed to a receive path for a node in a communication system such as a Radio Frequency Identification (RFID) system. In one aspect, the receive path includes a filter operable in multiple modes and configurable to have different bandwidths in the various modes of operation. For example, in one mode, the filter samples a DC component while configured to have a relatively wide bandwidth. As another example, the filter may be operated in another mode to hold the sampled DC component while the filter is configured to have a zero or close to zero bandwidth. As yet another example, the filter may be operated in still another mode to filter received signals and cancel the sampled DC offset from the received signals while configured to have a relatively narrow bandwidth. Additional embodiments are described and claimed.
