Resistivity of metal layers and vias IBM0.13

To be noticed:

1/. Very high resistivity of CA via!!
2/. Via resistivity higher than CA ~ cst.
3/. Gain a factor 10 by going higher than MQ/MG!!

Linearity & noise of the digital conversion for Psec4 (red) vs Psec3(blue)

Full ADC cell simulator

Accumulated design knowledge allow today for a: low-noise/high-linearity ADC cell (sampling+comparator). Using Virtual ADC and Virtual White Noise Source (Verilog-A) in simulation allows fast/accurate/extensive ADC simulation (new!).
