Abstract :
A low-voltage RF CMOS receiver front-end for energy harvesting Wireless Sensor Node (WSN) is presented. A MOSFET-only wideband balun LNA, with noise and distortion cancelling, is designed to work at 0.6 V supply voltage, in conjunction with a passive mixer. The passive mixer works in current mode, allowing a minimal introduction of noise and a good linearity. The receiver front-end reaches a total voltage conversion gain of 31.5 dB, a 0.1-5.2 GHz bandwidth, an IIP3 value of -1.35 dBm, and a noise figure inferior to 32.6 dB. The total power consumption is 1.95 mW.
