Accurate Shielded Interconnect Delay Estimation by Reconfigurable Ring Oscillator.

Shielding, which is used in VLSI designs to prevent noise interference from the cross-coupling capacitance between adjacent signals can also be used to tune the propagation delay of the clock signals in designs operating at low GHz frequencies. This paper presents a detailed design for a 16-nm ring oscillator with built-in reconfigurable shielding, and a delay estimation methodology. Together thes...
