• curprev 22:1322:13, 28 December 2024 Em3rgent0rdr talk contribs 15,276 bytes +124 is a bit clearer to show this signum as x_i-1 being compared to x rather than x_i-1 - x being compared to zero. Spell out "sgn" so it clearer that "sgn" is signum. Write in plain English sentence what this signum is doing. undo Tag: Visual edit

• curprev 19:5419:54, 28 December 2024 Em3rgent0rdr talk contribs 14,972 bytes +2,516 →Charge-redistribution successive-approximation ADC: added citations to two application notes, named each step, clarified some steps (e.g. about what happens for subsequent iterations) and added missing step "Update Switch" which is necessary for updating the estimated voltage. undo Tag: Visual edit
• curprev 08:1608:16, 28 December 2024 Em3rgent0rdr talk contribs 12,456 bytes +121 →Charge-redistribution successive-approximation ADC: removed some unnecessary wording and added a few missing important tidbits (like that there is a duplicate of the smallest capacitor and that the positive input of the comparator is grounded). Made the list nested to make structure of the algorithm clear. undo Tag: Visual edit
• curprev 06:5706:57, 28 December 2024 Em3rgent0rdr talk contribs 12,335 bytes −48 →Algorithm: move important stuff about circuit inaccuracies here to be right after the algorithm so can clarify that the the algorithm is "ideal". Add how the accuracy of the DAC is important. Shorten wording on the inaccuracies and introduce ENOB. undo Tag: Visual edit
• curprev 06:2706:27, 28 December 2024 Em3rgent0rdr talk contribs 12,383 bytes +7 →Algorithm: calling s(x) to be a "binary" signum function, to distinguish it from the signum function described in signum function which has 3 output levels. undo Tag: Visual edit
• curprev 06:1506:15, 28 December 2024 Em3rgent0rdr talk contribs 12,376 bytes +58 →Algorithm: tieing this algorithmic wording of s(x) to the actual circuit schematic by saying "s(x) represents the operation of the comparator mathematically..." undo Tag: Visual edit

• curprev 06:0606:06, 28 December 2024 Em3rgent0rdr talk contribs 12,300 bytes −479 →Algorithm: Plain english writing for the algorithm, shortening dramatically.
