That's how all conductors work, not just "in chips due to layers of conductors and insulators". The thing is that in most situations you just model the conductor away as a "perfect ideal wire" and everything usually just works since you don't care about these small delays and/or you have very high power. But when you enter sub-nanosecond and/or sub-mW territory...

- tom-thistime 5y agoYou're always driving a waveguide that has inductance and capacitance per unit length. But when resistance is high enough you are just charging a big distributed capacitor. It's a different regime from the high-conductivity situation (which looks like a transmission line). Either picture could apply at sub-ns speeds, it depends mainly on the resistance.
