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 10 Mbit/s in the 17 GHz band. A high-band FM-UWB receiver demonstrator, which achieves a measured sensitivity of -84.3 dBm at 100 kbit/s while consuming just 6 mW is also...
A Ka band low-noise amplifier in a 90-nm bulk CMOS technology is presented. A thin-film microstrip line with ground sidewalls is used for signal distribution, matching and load resonators. The low-noise amplifier comprises two identical cascode stages, with inter-stage matching as gain boosting. The gain boosting circuit improves the gain by 20% and the noise performance by 27% of the cascode LNA...
