本文探讨了两种仿真方法，用于评估comparator的input referred noise。第一种方法称为Transient noise，通过仿真分析，展现了当输入电压微小差异时，噪声如何导致错误输出脉冲出现，进而计算出正确的counts数量，结果显示正确counts约为84%。第二种方法是PSS+Pnoise，其优势在于一步就能计算出input referred noise...
现在我们需要将这个在comparator输出采样得到的噪声除以一个gain得到input-referred noies。“Keeping Things Quiet: A New Methodology for Dynamic Comparator Noise Analysis”文中提出的计算gain的方法为直接用50mV除以100uV得到的Gain=500。前者为进行noise采样时comparator的输出电压,后者为我们之前在comparator输入端所加...
perform the simulation using the expression: pow(integ(pow(clip(getData("out" ?result "pnoise_sample_pm0") 1 fs/2) 2)) 0.5), substituting fs/2 with the actual value.The noise we obtain is then normalized to an input-referred noise level. The gain calculation, as described...
A successive approximation register analog-to-digital converter (SAR ADC) includes a comparator with low input referred noise that uses a small capacitor array for improved communication speed. The comparator includes a cross-coupled pair of transistors, a first input transistor, a second input ...

Noise analysis techniques are applied to the prototype CBSC gain stage to arrive at, a theoretical noise power spectral density (PSD) estimate for the prototype pipeline ADC. Theoretical predictions and measured results of the input referred noise PSD for the prototype are compared showing that the...
The cascoded integrator dynamic residue amplifier (CIDRA) achieves a gain of 30dB with THD of 47dB (11 mV pp input). The input referred noise across tem- perature and process corner is 55 µV and it operates at a frequency of 500MHz while the energy consumption is 390 fJ. The low...
The comparator is analyzed and compared to its prior art in terms of energy consumption and input referred noise voltage. First-order equations are presented that show how to optimize the pre-amplifier for low noise and high gain. Both the dynamic bias comparator and the prior art are ...
