For a threshold of 1V and a temperature rise of 35C (35C to -70C) an offset of 5,5mV has been measured. The linear proportion of the +-150uV per 1°C. For a threshold of 1V and a temperature rise of 35°C (35°C to +70°C) an offset of 5,5mV has been measured. The linear proportion of the thermal variation can be compensated which results in a voltage rise of only -500uV for a temperature rise of 35C. +500uV for a temperature rise of 35°C. The compensation value of 0x02c0 was determined by measurement. To set the compensation value use the padiwa.pl script. For example ``./padiwa.pl 0x303 0 comp 02C0''. -\begin{figure}[pwoc] +\begin{figure}[htp] \centering - \includegraphics[width=0.6\textwidth]{figures/padiwa_thresh_without_compensation.pdf} + \includegraphics[width=0.8\textwidth]{figures/padiwa_thresh_without_compensation.pdf} \caption[]{Temperature dependence of the threshold without internal compensation.} \label{fig:pad_without_calib} \end{figure} \begin{figure}[htp] \centering - \includegraphics[width=0.6\textwidth]{figures/padiwa_thresh_with_compensation.pdf} - \caption[]{Temperature dependence of the threshold without internal compensation.} + \includegraphics[width=0.8\textwidth]{figures/padiwa_thresh_with_compensation.pdf} + \caption[]{Temperature dependence of the threshold with internal compensation.} \label{fig:pad_with_calib} \end{figure} -- 2.43.0
