Hi everyone,
I want to collect some inputs and maybe start a discussion here on what are your best practices when handling complex matching structures.
Often I see people struggling with complex matched MOS arrays on whether to simplify the pattern to have a cleaner routing and therefore less parasitics; or when to keep the pattern more distributed to improve the matching.
Since the parasitics can be easily extracted and backannotated, but the mismatch due to pattern and devices location not, how do you normally handle these two competing aspects?
