Abstract
A charge balance type of photodiode array uses parallel A/D conversion in each channel of the photodiode array. The charge caused by the photocurrent of a photodiode in each channel is removed in predetermined charge packets provided by a dumping circuit and the binary encoded number of delivered charge packets corresponds to the actual photocurrent. Charge balance photodiode arrays have a wide variety of applications. It is therefore useful to adapt photodiode arrays to the specific requirements of an individual application. The intention therefore provides a photodiode array having at least one switching circuit to vary signal processing parameters such as a gain factor g or an attenuation factor k. This improvement facilitates a multifunctional photodiode array for a plurality of different applications.
