Analog performance of Si junctionless tunnel field effect transistor and its improvisation using III–V semiconductor

Abstract

In this paper, the analog performance of a Si double gate Junctionless Tunnel Field Effect Transistor (DG-JLTFET) has been studied and improvised using a ternary III–V semiconductor compound, indium aluminium arsenide. The analog performance parameters are extracted using device simulations and also compared with the Si JLTFET. We show that III–V JLTFET delivers much better performance parameters, in comparison to Si JLTFET, which includes transconductance generation efficiency (G_m/I_D), intrinsic gain (G_mR_o) and unity gain frequency (f_T) along with various gate capacitances.
