Multichannel Programmable Readout IC for Photodiodes Array

This paper describes the design of the 17-channel readout integrated circuit targeted to front-end operation for photodiodes array. Proposed system contains an analog frontend electronics digitally configured using built-in Serial Peripheral Interface. Each signal channel has been designed for one particular set of photodiodes. Chip was designed and fabricated utilizing CMOS 0.18 μm technology and occupies area of 4960 μm × 1525 μm. Total current consumption is expected to be less than 33 mW (with 3.3 V supply).
