Complementary tunnel gate topology to reduce crosstalk effects

Tunnel transistors are one of the most attractive steep subthreshold slope devices which are being investigated to overcome power density and energy inefficiency exhibited by CMOS technology. There are design challenges associated to their distinguishing characteristic which are being addressed. In this paper the impact of the non-symmetric conduction of tunnel transistors (TFETs) on the speed of TFETs circuits under crosstalk is analyzed and a novel topology for complementary tunnel transistors gates, which mitigates the observed performance degradation without power penalties, is described and evaluated.
