A fully integrated, 300pJ/bit, dual mode wireless transceiver for cm-range interconnects

A transceiver aimed at ultra-short range wireless links uses a dual-mode architecture to achieve interference robustness at ultra-low power. The receiver uses a direct-AM detection architecture combined with a high-pass baseband filter to suppress out-of-band interferers, but is reconfigured to use a mixer-high-pass filter cascade designed to suppress in-band blockers based on a real-time BER estimate. The system consumes 300uW at 1MBps (1.75mW at 16 Mbps) and can operate with a worst-case SIR of 13dB (referred to peak power).
