Fig. 9

Input/output waveforms measured at \(-20\) to \(60\,^\circ{\rm C}\). 5–6 waveforms measured at each temperature are superimposed so that the peak timing of the input waveforms is at 0 s. These waveforms show examples of input pulse heights of about \(200\), \(180\), \(150\), \(120\), and \(90 \,\mathrm{mV}\) and the weakest signal that can be detected by the comparator, respectively. For the experiments conducted at \(-20\,^\circ{\rm C}\), the comparator could not detect input signals with a pulse height of below \(90\, \mathrm{mV}\); these signals are thus not shown in panel a
