• 05:4905:49, 16 October 2024 diff hist 0 Log amplifier →True log amp: slight rewording current Tag: Visual edit
• 05:4505:45, 16 October 2024 diff hist −79 Log amplifier →Temperature compensation: less strong claim to just be "it will be compensated" because this really depends on specifics of the circuit. Tag: Visual edit

• 16:0616:06, 15 October 2024 diff hist −26 Roll-off →First-order roll-off: Give more digits to the 6 dB/octave approximation, so readers see how approximate it is. Deleting vague "within normal engineering required accuracy" because engineering accuracy is a relative term that depends on application and this one-third percent above 6 dB error may or may not be significant. Better to give the 20 dB/decade exact number rather than the approximate 6 dB/octave when have a choice. Tag: Visual edit
• 15:1515:15, 15 October 2024 diff hist +32 Log amplifier →Temperature compensation: add stat on the TI app note for its log conformity Tag: Visual edit
• 15:0115:01, 15 October 2024 diff hist +644 Log amplifier →Drawbacks: The Linear Technology citation was not exactly saying this and was talking about BJT-based converters, not the simple diode converter anyway. Moved that source instead to be a new Drawbacks section at the end of the Transdiode configuration and add some more points from that source, whose primary conclusion seems to be the claim that modern delta-sigma with digital calculation is superior. Add temperature proportional to kelvin too. Tag: Visual edit
• 14:3214:32, 15 October 2024 diff hist +20 Process variation (semiconductor) →Characterization: hyperlinked and removed unnecessary space and reformatted numbered list current Tag: Visual edit
• 14:1814:18, 15 October 2024 diff hist +209 Log amplifier →Drawbacks: add a temperature simulation I generated from LTSpice showing how much changes between 25C and 50C. Tag: Visual edit
• 02:5702:57, 15 October 2024 diff hist +135 Operational amplifier applications →Temperature-compensated compression: add a sentence on diode D1 current Tag: Visual edit
• 02:4502:45, 15 October 2024 diff hist +1 Operational amplifier applications →Temperature-compensated compression: move the temperature compensation transistors to be later. Tag: Visual edit
• 01:1201:12, 15 October 2024 diff hist −46 Operational amplifier applications →Temperature-compensated piecewise linear compression: renaming to avoid saying "linear compression" Tag: Visual edit
• 01:1101:11, 15 October 2024 diff hist +14 Operational amplifier applications →Piecewise linear output: renamed section to →Temperature-compensated piecewise linear compression: like caption Tag: Visual edit
• 01:0901:09, 15 October 2024 diff hist +3 Operational amplifier applications →Piecewise linear output: refer to this schematic by its caption Tag: Visual edit
• 01:0401:04, 15 October 2024 diff hist +83 Operational amplifier applications →Piecewise linear output: start with most general statements. Then separate the circuit shown with its own sub-sub-heading. Tag: Visual edit
• 01:0101:01, 15 October 2024 diff hist −23 Operational amplifier applications →Piecewise linear output: the source seems to be saying the diodes/transistor with resistor networks does compression, so rearrange sentences. Tag: Visual edit
• 00:5400:54, 15 October 2024 diff hist −8 Operational amplifier applications →Piecewise linear output: slight shorter rephrase Tag: Visual edit
• 00:5300:53, 15 October 2024 diff hist −1 Operational amplifier applications →Piecewise linear output: slight rewording Tag: Visual edit
• 00:5300:53, 15 October 2024 diff hist +266 Operational amplifier applications →Piecewise linear output: Clarify that this schematic is only for gain compression. Add sentence on how expansion may be done as inverse of compression. Tag: Visual edit
• 00:0900:09, 15 October 2024 diff hist +25 Operational amplifier applications →Piecewise linear output: Technical correction...Q2 and Q3 aren't technically "off" but rather they "produce very little base current" Tag: Visual edit
• 00:0200:02, 15 October 2024 diff hist +22 Operational amplifier applications →Piecewise linear output: little more clarity on the lines segment selection Tag: Visual edit

• 23:5923:59, 14 October 2024 diff hist −6 Operational amplifier applications →Piecewise linear output: minor correction. Tag: Visual edit
• 23:5623:56, 14 October 2024 diff hist +2,111 Operational amplifier applications →Non-linear: added temperature-compensated piecewise linear output section, described by Texas Instruments and National Semiconductor application notes. Tag: Visual edit
• 03:5203:52, 14 October 2024 diff hist −9 Precision rectifier didn't introduce "super diode" word yet, so adding it as another name instead. Tag: Visual edit
• 03:4703:47, 14 October 2024 diff hist −75 m Precision rectifier →Basic circuit: define "opamp" abbreviation and use it. Tag: Visual edit
• 03:3503:35, 14 October 2024 diff hist +200 Precision rectifier →Basic circuit: "there is a negative voltage on the diode" was vague. Not quite that "no current flows through the load" but rather that RL pulls Vout down to ground...that pulling down process itself is a flow of current through RL. Add just a bit more specific on how the negative feedback works "just enough current will flow through"... Tag: Visual edit

• 19:3819:38, 11 October 2024 diff hist +28 Log amplifier →Drawbacks: say this is another "architecture" Tag: Visual edit
• 19:3119:31, 11 October 2024 diff hist +83 Log amplifier →Basic opamp diode circuit: point to "True log amp" section...these are different implementations of a similar function. Tag: Visual edit
• 19:2519:25, 11 October 2024 diff hist +14 Log amplifier maybe not use bold for these different spellings of each term. If there are 3 different ways to spell the first word, and 3 different ways to spell the second word, than that is 9 different spellings...and that isn't even getting into prepending it with "true" or "baseband". Tag: Visual edit
• 19:1919:19, 11 October 2024 diff hist −22 Log amplifier to address all permutations of spellings, just say how log can be respelled and how can be called a "converter" too. Tag: Visual edit
• 19:1519:15, 11 October 2024 diff hist +36 Log amplifier →Drawbacks: rearranged slightly on arcsinh. Tag: Visual edit
• 19:1219:12, 11 October 2024 diff hist 0 Log amplifier →Drawbacks: call these inputs Tag: Visual edit
• 19:1219:12, 11 October 2024 diff hist +16 Log amplifier →Drawbacks: opps...again got this math wrong. Tag: Visual edit
• 19:1119:11, 11 October 2024 diff hist +24 Log amplifier →Drawbacks: slight correction on math Tag: Visual edit
• 19:0819:08, 11 October 2024 diff hist +830 Log amplifier →Drawbacks: add about how to deal with inputs around the size of Vt or smaller. Tag: Visual edit
• 18:4018:40, 11 October 2024 diff hist +224 Log amplifier logarithmic converter is another spelling. Add about negative domain maybe mirroring positive output. Really just some range of the input, cause non-logarithmic things often happen near zero and there is always the question about negative inputs. Tag: Visual edit
• 18:3118:31, 11 October 2024 diff hist +114 Log amplifier add other spellings of exponentiator. Tag: Visual edit

• 17:2317:23, 11 October 2024 diff hist +47 Log amplifier not all of them use voltage as input...in fact a lot of datasheets, particularly which use sensors as inputs or which are for low noise reasons use current as input instead. Tag: Visual edit
• 16:2816:28, 11 October 2024 diff hist +21 m Instrumentation grammar (needs period at end of sentence). Made hyperlinks. current Tag: Visual edit
• 16:2516:25, 11 October 2024 diff hist −16 Log amplifier spell out equation of power Tag: Visual edit
• 16:2216:22, 11 October 2024 diff hist −42 Log amplifier →Drawbacks: bulk resistance is not just silicon, just any real diode. Shorten my wording a bit. Tag: Visual edit
• 13:5113:51, 11 October 2024 diff hist +5 m Ćuk converter Stick to same singular grammar form as earlier "energy has" and "current has", so "voltage has", not "voltages have". Add punctuation to equations. Say this is for "each" inductor, not "the", cause there are two. current Tags: Visual edit Mobile edit Mobile web edit Advanced mobile edit
• 04:5904:59, 11 October 2024 diff hist +1 Log amplifier →Temperature compensation: "Such architectures" instead of "this" because the example LOG200 is slightly different than what the paragraph describes. Tag: Visual edit
• 04:5604:56, 11 October 2024 diff hist +6 Log amplifier slightly better grammar for this bullet point Tag: Visual edit
