Abstract: A high performance CMOS linear 288×4 readout integrated circuit (ROIC) is detailed in this paper. It is a large-scale mixed-signal circuit with time-delay integration (TDI) function to enhance the signal to noise ratio (S/N), and defective element deselection (DED) function to decrease the probability of bad columns. The other features include adjustable integration time, multi gain, bidirection of TDI scan, super-sample, and electrical test. Digital I/O ports aredesigned to control its work mode. It is fabricated using 1.2μm double poly double metal (DPDM) CMOS technology. The measured power consume is about 24mW at 5V supply.
