Two ultra low power wireless concepts are described in this paper. A high data rate receiver demonstrator consisting of LNA, sub-harmonic I/Q mixer and transimpedance IF amplifiers realizes an energy consumption of 1.75 nJ/bit at 10Mbit/s in the 17GHz band. A high-band FM-UWB receiver demonstrator, which achieves a measured sensitivity of −84.3dBm at 100kbit/s while consuming just 6mW is also described.
