Abstract
The margin of threshold voltage (VT ) for GaAs normally-off MESFET DCFL´s was numerically analyzed applying the equivalent inverter circuit model. The results show that the optimum (VT ) is 0.3 V. Quantitative relation between the margin and delay time is obtained as a function of (VT ). At (VT ) = 0.3 V, the margin is 0.28 V with tpd less than 100 ps for 0.5 µm gate length.
