Hello,

I am designing a voltage detector IC using 0.6um CMOS technology, which requires the supply voltage as high as >10V.

Pls give me any advises or references about power IC.

Is it possible to make a circuit with supply voltage > 10V?

Thanks
Yawei

YW,

  Also see the PolarFab page. They have a 0.5um process that supports
up to 40V. Are you trying to design a 10V power IC on a stnadard
CMOS process? Or has the process been enhanced for high voltage
applications? For example, does the process have thick gate oxide
for high voltage transistors? Is there an LDMOS or DEMOS device
available? The line width may not be as important as the structure
of the devices available.

                                                                       Sheldon

Yawei,

Even if the device is able to handle vds of 10V, there is a limitation on vgs, vgd and vgb due to oxide breakdown, I would recommend you to check the design rule manual for the process.
If the devices are not able to support, the there are techniques like cascoding the devices to limit the vds and run your circuit at higher supply.
