In this paper, a detailed investigation of the effects of varying dielectric constant of the gate dielectric on the analog performance of a tunnel FET is reported. Variation in gate dielectric constant is made for both constant physical thickness and constant effective oxide thickness (EOT). A high-k gate dielectric is found to yield improved analog performance when physical thickness is kept constant, which is due to increased gate capacitance. On the other hand, a low-k gate dielectric delivers better analog performance when EOT is kept constant.
