UMC MoM capacitors

EMX was used to design a number of inter-digitated MoM capacitors for UMC's design kit libraries. The detailed results were presented at the UMC booth at DAC '07.. This is an example of a typical common centroid capacitor. Agreement between measurement and simulation is excellent. EMX accurately simulates the tiny parasitic inductance of the MoM capacitors and also gets the resistance correct. The simulations were done by including the pad frames to avoid all artifacts due to de-embedding.
