2) The light source used is a 428 nm LED with following characteristics: tr > 1 µs, tf < 1 µs. The output waveform is
monitored on an osciloscope with tr > 100 ns, Zi = 1 MΩ, Ci < 20 pF. The rise time is defined as the time from the
10% to the 90% value, the fall time is defined as the time from the 90% to the 10% value.
3) PSRR is defined as 20 log (VDD(f) / VO(f)) with VDD(0 Hz) = 4.5 V and VO(0 Hz) = 2 V
