can i use I/O Mos to design the complete chip? (for UMC 0.13)
Mar 10^th, 2009, 3:00am

hi, is there anybody who is familiar with UMC cmos 0.13? i have to design a sensor readout circuit based on this technology. the power supply voltage is fixed to 3.3V. it looks that the I/O MOSFET fits the voltage requirement. but what i am not sure is that, is it allowed to design the complete chip, including the core parts with such I/O MOSFETS?

thanks.

But in general I think it is quite common to use thick-oxide transistors only for the analog circuitry. I don't think that this is prevented by design-rules. But I think you should find that rule in you DRM, if there is any. Cheers
