WebField Effect Transistors (FETs) were fabricated with gate lengths (L g) ranging from 4μm to 50nm. The FETs have total gate width (W g ) of 40 or 120μm. L g =100 nm devices show DC drain current I D =600 mA/mm (V GS =-3V, V DS =-10V) with transconductance g m =140mS/mm (V GS =-0.3V, V DS =-4V). WebNov 9, 2004 · Activity points. 1,062. ft of cmos. the definition of the ft is. the frequency where the current gain. drops to 1. So you have to connect the drain to a constant voltage and connect the gate voltage to a constant voltage that will providing appropriate bias condition to the device (it should operate in saturation and resonable drain current.).
