[sdiy] OTA-C4 bandpass filter topology

[Lanterman, Aaron D]

I made a little video about an “OTA-C4 capacitively coupled current conveyor” bandpass filter topology:

I learned about it last year while sitting in on the “Neuromorphic VLSI” class my colleague Jennifer Hasler taught.

Here’s the paper:

The designers had fixed filter banks in mind, but I think it might be interesting to make voltage controlled versions.
