Title: Innovations by Donald Edward Major
Introduction
Donald Edward Major is a prominent inventor based in Irvine, California. He has made significant contributions to the field of radio frequency identification (RFID) technology. With a total of 5 patents to his name, Major has developed innovative solutions that enhance communication between RFID devices.
Latest Patents
Major's latest patents include a Multi-protocol RF transceiver. This transceiver facilitates communication between an RFID reader and an RFID transponder (tag). The RFID reader employs an analog front end and a digital backend. In the receiver portion of the transceiver, the front end of the RFID reader utilizes a pair of down-conversion mixers to demodulate a received signal into in-phase (I) and quadrature (Q) components. Analog-to-digital converters (ADC) digitize the signal. A digital signal processor (DSP) in the backend processes the digital signal and employs a matched filter for data detection. The RFID tag receives an inductively coupled signal from the reader. The receiver portion of the tag uses a pulse/level detector that incorporates an analog comparator and a sample and hold circuit to detect the received signal. A digital decoder/controller decodes the incoming data and establishes a sampling clock for the pulse/level detector. An automatic gain control (AGC) circuit adjusts the receiver gain according to the received signal strength and controls the tuning of magnetic coupling circuitry.
