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.

Abstract ：
以设计输出电流为700 mA，静态电流为50μA，芯片面积为1.5 mm×2.0 mm的LDO线性稳压器为目标，提出的LDO电路利用基准电路的输出直接作为芯片的输出，用基准电路所固有的跨导放大器对输出进行检测并反馈至单级放大器，放大后输出至功率管的基极，控制功率管输出额定的电压和电流。无需冗余的误差放大器，使得环路补偿极为简单，不存在传统LDO的补偿难题。在电路上把传统LDO电路所需各个模块的功能糅合到了一个较为简单的电路中，大大减小了芯片面积，并且减小了静态电流。对电路进行了仿真分析并采用2μm 36 V Bipolar工艺生产实现，流片后的测试结果表明该芯片实现了大电流，微功耗，小体积的特性。
