Abstract :
A dedicated ultra-low power fully integrated FSK wake-up receiver (WuRx) for wireless body area network (WBAN) is implemented in 0.18μm CMOS technology with 0.7V supply. An injection-locking digitally-controlled oscillator (ILDCO) enables power-efficient front end amplification, and autocalibration of DCO by successive approximation resister (SAR) algorithm. The fabricated 1mm2 single chip WuRx consumes 45μW with a data rate of 312kb/s, providing an 80MHz reference frequency with 0.25% stability to the main transceiver for crystal-less WBAN sensor nodes.
