Netherlands 1 2 Minimizing the power consumption while maintaining performance is paramount in radio transceiver design for low-power wireless sensor network (WSN) applications. Given a sub-mW power budget, many radios have utilized amplitude modulation and envelope detection to eliminate the need for accurate frequency references and to reduce power consumption [1-4]. However, such radios suffer from poor frequency selectivity. They rely on front-end filters to reject out-of-band interference, while in-band interferers still corrupt the desired signal. This work introduces a new interference-rejection technique for ultra-low-power envelope detection radios. Instead of sending 1 carrier tone, the baseband (BB)
