Abstract

An RFID circuit comprises an RF carrier signal source (32) , and a hybrid coupled thereto operable to generate first, second and third phase-shifted RF carrier signals. The circuit comprises first (34) , second (36) , and third (38) mixers coupled to the hybrid each operable to multiply one of the first, second and third respective carrier signals and a backscattered modulated carrier signal and generate first, second and third baseband signals, respectively. The circuit comprises first, second, and third delay lines respectively coupled to the first, second, and third mixers and operable to generate first (BBl) , second (BB2) and third (BB2) delayed baseband signals. The circuit comprises logic coupled to the first, second, and third mixers and the first, second, and third delay lines and operable to detect substantially simultaneous data transitions in at least two of the first, second, and third baseband signals, and generating a reconstructed signal having a data transition in response thereto.
