动态比较器
By introducing a gain boosting circuit and clock signal control into the dynamic comparator, the transconductance of the transistor is dynamically adjusted, solving the problem of limited gain in traditional comparators and achieving higher gain and lower noise performance, making it suitable for high-speed and high-resolution applications.

Abstract
本发明提供了一种动态比较器，其包括动态放大器和锁存电路。动态放大器包括第一输入对、电流源和增益提升电路。第一输入对被配置为接收输入信号以在输出端产生放大信号。电流源耦接在第一输入对与第一参考电压之间。增益提升电路耦接在第一输入对与第二参考电压之间，并被配置为接收输入信号以选择性地向输出端注入电流或从输出端汲取电流。锁存电路耦接动态放大器，用于接收放大信号以产生输出信号。本发明提供的动态比较器可提供较高的增益。
