Next Generation Digital Front-End for Multi-Standard Concurrent Reception

• This article presents an architecture of a Digital Front-End Receiver (DFE-Rx) for the next-generation mobile terminals. A main focus is placed in flexibility, scalability and concurrency. The architecture is capable of detecting, synchronizing and reporting carrier-frequency offset, of multiple concurrent radio standards. The proposed receiver is fabricated in a 65nm CMOS low power high-VT cell technology in a die size of 5mm2. The synchronization engine has been measured at 1.2V and reports an average power consumption of 1.9mW during IEEE 802.11 reception and 1.6mW during configuration, while running at 10MHz.
