Abstract：

A　low　noise　multi-channel　readout　integrated　circuit　(IC)　which　converts　a　detector　current　to　analog　voltage　for　X-ray　cargo　inspection　is　described.　The　readout　IC　provides　32　channels　of　a　circuit　having　a　maximum　dynamic　range　of　15　bit　and　is　comprised　of　integrator　gain　selection,　timing　generator,　shift　register　chain,　integrator　array,　sample/hold　(S/H)　stage　amplifier　etc.　It　was　fabricated　using　0.6　μm　standard　CMOS　process,　and　occupies　a　die　area　of　2.7　×　13.9　mm2.　It　operates　at　1　MHz,　consumes　100　mW　from　a　5　V　supply　and　4.096　V　as　reference,　and　has　a　measured　output　noise　of　85　μ　Vrms　on　63　pF　of　integrator　gain　capacitance　and　440　pF　of　photodiode　terminal　capacitance　so　that　steel　plate　penetration　thickness　can　reach　more　than　400　mm.　©　2013　Chinese　Institute　of　Electronics.
