VOLTAGE WAVEFORM
NOTES: A. The input irradiance is supplied by a pulsed AlInGaP light-emitting diode with the following characteristics: λ_p = 635 nm,
t_r < 1 μs, t_f < 1 μs.
a _{B. The output waveform is monitored on an oscilloscope with the following characteristics: tr < 100 ns, Zi ≥ 1 MΩ, Ci ≤ 20 pF.}
