摘　　要：从高位数,低功耗MOS图象传感器发展的需要出发,对MOS图象传感器的自扫描电路进行研究。提出以一种带变容管自举电路的三管动态无比电路作MOS图象传感器的自扫描电路。该电路采用硅栅P-MOS工艺,是一种高速度,低功耗的动态无比电路。也是一种高位数列阵中的实用单元电路,它较好地解决了列阵功耗随位数增加而变大的问题。The paper studies a self- scanned circuit used in MOS image sensor with the demand of developing of high -order.low power disspation MOS image sensor and puts forward a kind of self -scanned circuit .which uses a three tramister dynamic nocomparing circuit whith a changing capacitor bootstrap circuit as MOS image sensor. The circuit adopted a silicon gote P -MOS technique, which is a high -speed low-dissipation dynamic no-coparing circuit. It is a practical unit circuit in the high -order array and solves the problem that the power dissipation of array rises with the increase of the array bite.
