From 7841162bd66886a13510aeab88bdc7a2861cbc64 Mon Sep 17 00:00:00 2001 From: occheung Date: Wed, 19 Jan 2022 12:27:36 +0800 Subject: [PATCH] 5432: remove symbols revert b9ce64ed. The remaining symbols are very standard (e.g. V, Z), so the symbol column is removed instead. --- 5432.tex | 44 +++++++++++++++++++++++--------------------- 1 file changed, 23 insertions(+), 21 deletions(-) diff --git a/5432.tex b/5432.tex index 2768923..982c30d 100644 --- a/5432.tex +++ b/5432.tex @@ -160,22 +160,23 @@ The specifications are based on the datasheet of the DAC IC and various information from Sinara wiki\footnote{\label{zotino_wiki}https://github.com/sinara-hw/Zotino/wiki}. \begin{table}[h] +\centering \begin{threeparttable} \caption{Output Specifications} -\begin{tabularx}{\textwidth}{l | c | c c c | c | X} +\begin{tabularx}{0.8\textwidth}{l | c c c | c | X} \thickhline - \textbf{Parameter} & \textbf{Symbol} & \textbf{Min.} & \textbf{Typ.} & \textbf{Max.} & + \textbf{Parameter} & \textbf{Min.} & \textbf{Typ.} & \textbf{Max.} & \textbf{Unit} & \textbf{Conditions} \\ \hline - Output voltage & $V_{out}$ & -10 & & 10 & V & \\ + Output voltage & -10 & & 10 & V & \\ \hline - Output impedance\repeatfootnote{zotino_wiki} & $Z_{out}$ & \multicolumn{4}{c|}{470 $\Omega$ $||$ 2.2nF} & \\ + Output impedance\repeatfootnote{zotino_wiki} & \multicolumn{4}{c|}{470 $\Omega$ $||$ 2.2nF} & \\ \hline - Resolution\repeatfootnote{dac} & $M_{V}$ & & 16 & & bits & \\ + Resolution\repeatfootnote{dac} & & 16 & & bits & \\ \hline - 3dB bandwidth\repeatfootnote{zotino_wiki} & $BW$ & & 75 & & kHz & \\ + 3dB bandwidth\repeatfootnote{zotino_wiki} & & 75 & & kHz & \\ \hline - Power consumption\repeatfootnote{zotino_wiki} & $P$ & 3 & & 8.7 & W & \\ + Power consumption\repeatfootnote{zotino_wiki} & 3 & & 8.7 & W & \\ \thickhline \end{tabularx} \end{threeparttable} @@ -186,30 +187,31 @@ In terms of output noise, it was measured after 15 cm IDC cable, IDC-SMA, 100 cm The DAC output during noise measurement is 3.5 V. \begin{table}[h] +\centering \begin{threeparttable} \caption{Electrical Characteristics} -\begin{tabularx}{\textwidth}{l | c | c c c | c | X} +\begin{tabularx}{0.8\textwidth}{l | c c c | c | X} \thickhline - \textbf{Parameter} & \textbf{Symbol} & \textbf{Min.} & \textbf{Typ.} & \textbf{Max.} & + \textbf{Parameter} & \textbf{Min.} & \textbf{Typ.} & \textbf{Max.} & \textbf{Unit} & \textbf{Conditions / Comments} \\ \hline - DC cross-talk\repeatfootnote{zotino21} & $\frac{V_X}{V_{out}}$ & & -116 & & dB & \\ + DC cross-talk\repeatfootnote{zotino21} & & -116 & & dB & \\ \hline - Fall-time\repeatfootnote{zotino21} & $t_{fall}$ & & 18.5 & & $\mu$s & 10\% to 90\% fall-time \\ - & & & 25 & & $\mu$s & 1\% to 99\% fall-time \\ + Fall-time\repeatfootnote{zotino21} & & 18.5 & & $\mu$s & 10\% to 90\% fall-time \\ + & & 25 & & $\mu$s & 1\% to 99\% fall-time \\ \hline - Negative overshoot\repeatfootnote{zotino21} & $PO_{fall}$ & & 0.5\% & & - & \\ + Negative overshoot\repeatfootnote{zotino21} & & 0.5\% & & - & \\ \hline - Rise-time\repeatfootnote{zotino21} & $t_{rise}$ & & 30 & & $\mu$s & 1\% to 99\% rise-time \\ + Rise-time\repeatfootnote{zotino21} & & 30 & & $\mu$s & 1\% to 99\% rise-time \\ \hline - Positive overshoot\repeatfootnote{zotino21} & $PO_{rise}$ & & 0.65\% & & - & \\ + Positive overshoot\repeatfootnote{zotino21} & & 0.65\% & & - & \\ \hline - Output noise\repeatfootnote{zotino27} & & & & & & \\ - \hspace{18mm} @ 100 Hz & & & 500 & & nV/rtHz & 6.9 Hz bandwidth \\ - \hspace{18mm} @ 300 Hz & & & 300 & & nV/rtHz & 6.9 Hz bandwidth \\ - \hspace{18mm} @ 50 kHz & & & 210 & & nV/rtHz & 6.9 kHz bandwidth \\ - \hspace{18mm} @ 1 MHz & & & 4.6 & & nV/rtHz & 6.9 kHz bandwidth \\ - \hspace{18mm} $>$ 4 MHz & & & & 1 & nV/rtHz & 6.9 kHz bandwidth \\ + Output noise\repeatfootnote{zotino27} & & & & & \\ + \hspace{18mm} @ 100 Hz & & 500 & & nV/rtHz & 6.9 Hz bandwidth \\ + \hspace{18mm} @ 300 Hz & & 300 & & nV/rtHz & 6.9 Hz bandwidth \\ + \hspace{18mm} @ 50 kHz & & 210 & & nV/rtHz & 6.9 kHz bandwidth \\ + \hspace{18mm} @ 1 MHz & & 4.6 & & nV/rtHz & 6.9 kHz bandwidth \\ + \hspace{18mm} $>$ 4 MHz & & & 1 & nV/rtHz & 6.9 kHz bandwidth \\ \thickhline \end{tabularx} \end{threeparttable}
