摘要
本文讨论了一种高速CMOS比较器,采用前置放大器、锁存器和输出驱动级联的结构,通过优化传输速度、增益和失调电压,采用SMIC0.25umCMOS工艺,用CadenceSpectre模拟器仿真,结果表明最小分辨率为1mV,工作频率达到50MHz,功耗2mW。
This paper describes a high resolution , high speed comparator which use a preamplifier cascade the latch and output driving . Fabricated in a standard 0.24um CMOS process , it is simulated with Spectre . After optimizing the delay time , the gain and the offset voltage , the result indicates that the resolution is lmV . The operation frequency could be as high as 50MHz , the power consumption is 2mW.
