Analog circuit scaling

[jbeniston]

Is there a typical scaling factor for analog CMOS circuits? E.g. something equivalent to that which says for digital circuits, area halves with each process node. So if I had an analog circuit that was 0.5mm^2 in a .18u process, how could I estimate the area in a .13u process. Only looking for a first order estimate. Thanks.

If your circuits are all 3V devices, there will be no scaling effects from 0.18um process to 0.13um process.

If your circuits are all 1.8V device, there will be some scaling effects from 0.18um process to 0.13um process.

Usually, there will be about 40~50% shrink for all digital circuit.
For analog circuits, I think there will be about 30% most shrink.

Just my experience.
