<p><span class="h-card" translate="no"><a href="https://chaos.social/@gsuberland" class="u-url mention">@<span>gsuberland</span></a></span> yeah i figured that you&#39;re using the FET as a modulator but it wasn&#39;t completely clear for what purpose</p>

<p>I&#39;m not even sure how to properly describe this. &quot;nonlinear modulating low-pass filter&quot;, I guess?</p><p>the core of it is that the MOSFET is a big power FET with a ton of Cgs. combined with the 220k resistor, you get a low-pass filter. the channel A voltage is adjusted by the opamps to keep the MOSFET sub-threshold.</p><p>except the really evil part of this is that the MOSFET&#39;s gate capacitance is dependent on Vds. so channel B modulates Vds, adjusting the filter&#39;s cutoff frequency.</p>

<p>we have a winner!</p><p><a href="https://aus.social/@nickzoic/113921516097962178" target="_blank" rel="nofollow noopener noreferrer" translate="no"><span class="invisible">https://</span><span class="ellipsis">aus.social/@nickzoic/113921516</span><span class="invisible">097962178</span></a></p>

<p>alright, let&#39;s go with one final hint that&#39;s REALLY going to bake your noodle.</p><p>the MOSFET never turns on. at all.</p>

<p>ok, a few of you have gotten very close so I&#39;m going to provide a bit more help</p>

<p>a fun kind of reverse engineering tactic that I practice probably more than I should is a version of The Scream Test (which is the principle that the easiest way to find who &quot;owns&quot; a server is to turn it off and see who screams): if you don&#39;t know what some code does, break it. and see what screams.</p>
