An accurate large-signal SPICE model for Resonant Tunneling Diode

Resonant Tunneling Diode (RTD) is a promising device that can be used in the design of ultra-high speed circuits. Also the Negative Differential Resistance (NDR) characteristic of RTD showed a significant reduction in logic circuits' size and complexity. This paper proposes a new accurate and less complexity large signal RTD SPICE model for analyzing circuits containing RTD. In addition, a straightforward parameters extraction routine using MATLAB program is developed. Some important applications are simulated and verified using the new model.
