| Abstract: | 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 1mV . The operation frequency could be as high as 50MHz , the power consumption is 2mW. |
