Circuit design with adjustable threshold using the independently controlled double gate feature of the Vertical Slit Field Effect Transistor (VESFET)

Abstract

The recently introduced Vertical Slit Field Effect Transistor allows for adjusting its threshold voltage through independent controllable gates. This feature can be applied to a broad range of circuits. In this paper two examples are presented. First, a ring oscillator with a wide frequency tuning range and second, a Schmitt trigger with a controllable hysteresis.
