Temperature dependence of Harmonic Distortion on TVS Structures

This is study investigates the temperature-dependent non-linear behavior of TVS structures by measuring and simulating harmonic distortion. Motivated by simulation and measurement, we identified two sources for this temperature dependency. First, due to the highly temperature-dependent leakage current, we suggest that a temperature shift may change internal DC potentials, which can explain a shift in harmonic levels. Secondly, we observed that non-linear junction capacitance changes with temperature. We suggest that these two effects may explain the observed dependency on temperature. In order to measure separate effects, we measured on custom TVS test structures.
