Tool/software:
I plan to use ADS1299 to design a PCB acquisition board for collecting EEG signals. I want to know the impedance between the electrode and the channel pin of ADS1299, as well as the impedance in other places. My main goal is to achieve impedance matching. Design PCB routing parameters such as line width and copper thickness based on the required impedance. So how can I determine the impedance required for ADS1299.For example, what is the impedance of the PCB board diagram in the design manual of ADS1299EEG-FE below? And what is the line width?
