Nice write-up as usual, Chuck! I'll generaly try and avoid using charge pumps as much as I can.
Apart from the headroom concerns, does the peak detector rely on the higher voltage available?

After getting reacquainted with Bill's Law I have this one working on my breadboard.
Most of my germaniuns are too low gain, but some of them sound very sweet
This is a bit off topic, but are you guys familiar with coral.AI boards?
They have a microcontroller board with TPU that I reckon should be able to run larger neural models (of course there's the problem of ADC/DAC that is already solved with the seed)
