Hello,
It is very basic to know that poly has much resistance as compared to metal, hence when routing a current signal we should think about the voltage drop on the poly connector,
however, if routing a biasing voltage like the connection between the MOS gates, here there is ideally no current, hence no voltage drop problem,
so what will be the limitation of using the poly routing here?
I have a big matched transistor array in the length of 200 µm, and for no reason I am little afraid about connecting the gates using poly, that is why I switch to metal 1 at event segments of the array.
I am looking forward for your discussion
Best Regards
