Hello,
I see from the industry chip, for instance, op-amp chips that the range of supply voltage can be a wide range. For example, consider the analog comparator MCP6549 from Microchip Technology. The supply voltage is from 1.6 V to 5.5 V.
I am designing with CMOS 0.35 µm standard process, but the usual range I have in my design for proper operation is maximum between 2.8 V to 3.6, else I start to have problem in my cascoded branches for low voltage and for the higher voltage I will be restricted by the technology so I am not allowed to use higher voltage like 5 V.
So how the industrial chips are making the supply voltage wide, do they use internal LDO or something related to the technology?
Thanks
