curprev 22:0922:09, 27 January 2025 Em3rgent0rdr talk contribs 33,127 bytes +64 There must have previously been a diagram showing non-idealities, so I've readded one back with a short caption identifying some of them. Also simply having a "large" gain and input impedance isn't enough to be "considered ideal", but rather the unreachable "ideal" would have infinite gain and infinite input impedance. undo Tag: Visual edit

curprev 18:3418:34, 24 September 2024 Em3rgent0rdr talk contribs 30,471 bytes +71 →Exponential output: more that Vd is large relative to Vt, not that Vd is just above zero. Give thermal of 26 mV at room temperature as reference. For instance, the approximation error around 120 mV is still 1% off. undo Tag: Visual edit
curprev 18:1618:16, 24 September 2024 Em3rgent0rdr talk contribs m 30,400 bytes +10 →Exponential output: Use approximately equal Latex symbol where appropriate. undo Tag: Visual edit
curprev 17:3917:39, 24 September 2024 Em3rgent0rdr talk contribs 30,390 bytes −214 →Logarithmic output: move →Exponential output: first cause is easier to explain, and cause then can easily transition to describing log out as inverting the exponential function and can just describe the Schokley diode equation and its approximation once. undo Tag: Visual edit

curprev 04:1604:16, 20 August 2023 Em3rgent0rdr talk contribs 30,276 bytes +424 →Inverting integrator: there needs to be add the V_error. Also this circuit only behaves as integrator significantly above its new cutoff-frequency of 1/(2piRfCf). Need to point out that this is really more like a standard lowpass filter. undo Tag: Visual edit
