P/N length mismatch may be inevitable (due to pin out for example). Adequate P/N lengthmatching should be considered. Any technique to achieve matching should consider thefollowing:• P/N length matching should occur as close as possible to where the mismatch happens• Serpentine/sawtooth routing is a way to reduce P/N length mismatch, but shape ofserpentine/sawtooth should be optimized
