Abstract :
Low noise high-frequency analog operation of small geometry silicon MOSFETs is demonstrated. By scaling gate length down to 0.3-sub 0.1 /spl mu/m regions, excellent low noise figure of 1.5 dB at 2 GHz was obtained with low drain current of 0.3 mA//spl mu/m at f/sub T/ value of 20-65 GHz-the same level as today´s high performance silicon bipolar transistors in research level. Even at low voltage operation such as 0.5 V, extremely high cutoff frequency of 48 GHz was realized by sub 0.1 /spl mu/m gate length nMOSFETs. Such low voltage operations allow one order of magnitude smaller power consumption compared with 2 V power supply voltage.
