CMOS图像传感器LVDS驱动器电路设计
资料介绍
为解决在2.5 V供电下的LVDS（Low Voltage Differential Signaling）驱动器处理1.2 V数字信号时,由于传统电平转换电路性能较差,且易产生误码的问题,设计了一款应用于CMOS（Complementary Metal Oxide Semiconductor）图像传感器芯片的LVDS接口电路,该芯片中数字电路采用1.2 V供电,LVDS驱动器使用2.5 V供电。笔者提出两种电平转换电路方案,用于解决该问题。方案1将1.2 V数字信号进行电平转换,再使用D触发器对转换后的信号进行采样,从而避免误码的产生;方案2使用迟滞比较器作为电平转换电路。设计采用Tower Jazz 65 nm CMOS工艺进行流片验证。经过测试,两种方案均有效地解决了LVDS驱动器误码的问题。
In order to solve the problem of processing 1. 2 V digital signal in LVDS（ Low Voltage Differential Signaling） driver with 2. 5 V power supply,due to the poor performance of traditional level conversion circuit and the problem of bit error,an LVDS interface circuit for CMOS（ Complementary Metal Oxide Semiconductor）image sensor chip is designed. The digital circuit is powered by 1. 2 V and the LVDS driver is powered by 2. 5 V. This paper proposes two level shifting circuit schemes to solve this problem. In the first solution,hysteresis comparator is used as the level shifter. In the second ...
