Zusammenfassung:	This article presents a high-sensitivity and high energy efficiency wake-up receiver (WuRx) based on an injection-locked oscillator (ILO) and an envelope detector to provide the capabilities of reliable demodulation for ON-OFF keying (OOK), binary frequency shift keying (BFSK), and differential binary phase shift keying (DBPSK) demodulation schemes. A 54- \mu \text{W} 433-MHz multimode WuRx is implemented in a 0.18- \mu \text{m} CMOS process. For a data rate of 200 kb/s and a bit error rate (BER)
