    Abstract: Apparatus, system, and method for multi-class wireless receiver are described. The multi-class receiver includes a first down-converter coupled to an input port, a filter coupled to the first-down converter, and a second down-converter coupled to the filter. In a first mode, the filter is configured as a first filter and the second down-converter is disabled. In a second mode, the filter is configured as a second filter and the second down converter is enabled. The system includes a wireless module and a wireless transceiver in communication with the wireless module. The method includes receiving multi-class RF signals, converting at least a first class of RF signals in a first mode of operation, and converting at least a second class of RF signals in a second mode of operation with said multi-class receiver.

    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.

    Abstract: A modulator is provided in operative engagement with a sensor element having a plurality of electrodes. The modulator has a single-bit quantizer electrically connected to a digital accumulator. The accumulator accumulates output information received from the single-bit quantizer. The accumulator converts the accumulated output information received from the single-bit quantizer to a multi-bit feedback signal and sends the multi-bit feedback signal in a primary feedback loop back to the sensor element. The quantizer sends a single-bit feedback signal in a secondary feedback loop back to a point before the quantizer.
