2 Limiting Capacitance (LC)

Figure 4 shows different range cap curve at different output load.
LC cap is coming out to be the best estimation of input cap. Correlation data shows
LC cap correlates much better than traditional input cap.
Table 1 is the correlation result (Tradition Cap vs LC). Negative correlation
number shows that STA is faster than HSPICE simulation. The Liberty with LC
capacitance gives out very accurate correlation than the Liberty with traditional
capacitance.
