As CMOS technologies reach their physical limits, advanced devices and circuit structures are needed to enable compact circuit design. Carbon nanotube field-effect transistors (CNTFETs) are compelling alternatives to MOSFETs, and their ambipolarity provides a route to reduce device count through higher expressive power with dual-gate CNTFETs. However, previous models do not permit switching of the...
Current through ambipolar carbon nanotube field-effect transistors (CNTFETs) can be controlled by two independent gates, enabling highly expressive XOR-based logic circuits. To promote efficient circuit design, it is important to develop an easy-to-use SPICE-compatible model for these dualgate ambipolar CNTFETs. This paper therefore introduces a closed-form model that matches the experimentally demonstrated...
