Abstract

In an infrared detector provided with a photodiode, when the temperature of the photodiode is lowered to its operating temperature, the photodiode is forward biased. During forward biasing of the photodiode, injection of a majority carrier current takes place through the photodiode. The majority carriers mask a part of the defects of the photodiode. The acquisition phase is then performed by reverse biasing the photodiode.
