Measurements are made with R
L
= 10 kΩ between output and ground.
Optical measurements are made using small-angle incident radiation from an LED optical source.
The input irradiance E
e
is supplied by an AlInGaP LED with peak wavelength
λ
p
= 635 nm
The input irradiance E
e
is supplied by a GaAlAs LED with peak wavelength
λ
p
= 880 nm
Irradiance responsivity is characterized over the range V
O
= 0.05 to 2.9 V. The best-fit straight line of Output Voltage V
O
versus
irradiance E
e
over this range will typically have a positive extrapolated V
O
value for E
e
= 0.
