Has anyone been playing with making analog circuits out of digital standard cells at all?
That is more or less the goal of the FaSOC project.
ahh okay, i'll check it out, thanks
Yes, I have designed oscillators and dac’s so far. I will also be doing filters soon.
I find the OSU models the most useful so far because the inverter is better balanced and the models are more detailed - presumably because they are layout extracted. The ring oscillator link above uses the particular design of the sky130 mux2i. I haven’t seen the OSU muxes which will likely use pass transistors so they may not be as useful for analog.
I am experimenting now with improving analog performance by changing the bulk biasing of the sky130 cells. I will report on that soon.
