Hi All, I have updated the documentation page for USA-1 project. https://github.com/shakyaj/flicker_cancel. We are still working on layout but from current estimates, we should fit within 100umx100um space. This is assuming we don't need a driver/buffer to do the noise measurement. I am right now assuming 2pF load, but not sure how much more load will be on PCB. Does anyone have any idea ?
