1, Dynamic latch comparator (slicer), rather than the traditional continuous time comparator, uses the "metastability" instead of "gain" or "bandwidth" to characterize the circuit design. [1]
和放大器/连续比较器不一样,动态比较器使用“metastability”来衡量(某速度下的)增益和带宽。
2, To simulate the metastability, apply a small voltage (~10uV) to the slicer input, then toggle the clk to let the slicer sense. Then the output voltage waveform is monitored and the time for the waveform to change from latching node Vx=V1=1x to Vx=V2=2.718x(the constant 'e') is measured. (Vx=1x, e.g., Vx=10uV as an arbitrary small voltage, any small voltage is OK)
要仿真亚稳态,在slicer的输入端给一个小输入,然后把CLK振起来让比较器采样。监测输出电压波形,记录下输出电压从一个值变化到另一个更大值的时间,比如从10uV变化到27.18uV。
3, The time from Vx
