An Ultra-Low-Voltage and Ultra-Low-Power 2.4 GHz LNA Design
MetadataShow full item record
In this paper, ultra-low-voltage and ultra-low-power circuit techniques are presented for CMOS RF front-ends. By employing a modified current-reused architecture, the low-noise amplifier (LNA) can operate at a very low supply voltage with microwatt power consumption while maintaining reasonable circuit performance at 2.4 GHz. Using a TSMC 0.18 um CMOS process, from the simulation results, the fully integrated LNA exhibits a gain of 14.4 dB and a noise figure of 1.6 dB at 2.4 GHz, operated at a supply voltage of 0.9 V, the input matching (S11) is –18.1 dB while consumes only 960 μW. example.
