Abstract :
A novel integrated CMOS smart detector which is intended to provide flexible low noise amplification and multiplexing component is presented in this paper. Low level current output devices, such as a photodiode array, can be directly connected to its input. It has 64 channels, and each channel has a photo-sensitive preamplifier and the ability to provide correlated double sampling (CDS) and holding. This chip may also be used as general-purposed multi-input multiplexer for medical, scientific, or industrial instrument applications. There are no similar products reported in China yet. The test results show that the expected functions of the chip can be fulfilled.
