摘　　要：主要研究了一种多路输出及读出顺序可控电路的实现方法。该电路除实现单路传输外,在支持并行传输的情况下可以实现两路和四路同时传输,且读出顺序可控。该电路经仿真表明具有完整的功能,并在CSMC0.5μm的工艺下得到实现,目前用于一款红外焦平面读出电路中。该电路提高了数据传输速率,在大规模数据阵列的情况下作用尤为明显,同时其读出顺序可控的功能满足了多种工作的要求。A circuit of multiple read outs and controllable of reading out sequence is presented. Besides supporting reading out in single channel,the circuit can also transmit data in 2 or 4 channels,if parallel transmission is supported, and the read out sequence can be controlled. The circuit has been validated to have the whole function with simulation and fabricated in CSMC 0. 5/~m CMOS technology. It has been used in one Infrared Focal Array Read Out Circuit. This circuit improves the data transmission rate, extremely effective in the use of large scale of data arrays, and its controllability of read out sequence satisfies many demands.
