Hello.
Can someone please explain to me why negative voltages are not commonly used with CMOS IC chips? Why is the technology always described as being 0-3.3 V or 0-5 V for example?
I ask because my colleague has found a topology which is for a 0.35 um process that works for -1.5 V to 1.5 V however for 0 -3.3 V the same topology does not work. Surely having negative voltages available makes life simpler?
Thanks
