A new approach for a battery-less 915MHz ISM band wake-up receiver with digital decoder for wireless sensor network is designed and presented. The proposed receiver architecture is based on a differential rectifier with gate-driver circuit using an ON-OFF Keying modulation for the input signal. To enhance the power conversion efficiency (PCE) of the rectifier for the low input power level, appropriate gate-drive voltages for each stage of the rectifier are generated using a chain of auxiliary floating rectifier cells. The wake-up receiver is designed in 0.18/mu m CMOS technology and achieves a sensitivity of 34 dBm at 0.8V for a 100 kbps.
