In this section, we present the two dimensional iso-thermal simulation results with the I-V characteristics of the regenerative diode at different temperatures. In addition, we also compare the characteristics of the regenerative diode with that ofthe ofJBS rectifier at different temperatures. In the simulations, we considered the same dimensions and doping concentration of the n- drift region for both the devices, which support 100V. The simulations have been performed in the 'Device Simulation for Smart Integrated Systems' (DESSIS) which is an ISE-TCAD tool [6]. The forward I-V characteristics ofthe regenerative diode at 300k are shown in Fig. 5. As mentioned earlier regenerative diode is a normally ON device. The current flow starts from without threshold voltage and increases as the anode becomes positive. It exhibits a linear relationship between the current and voltage until the voltage across the device reaches 0.95V.
