3.3v to 5v
I designed a chip with 3.3v/5v process. The digital part is working with 3.3v.
but the analog part need 5v power source, How can I raise the signal of digital output from 3.3v to 5v? Is there any good suggestion?
I tried a simple inverter. Though it can work, the pmos could not be shut down since the input is only 3.3v. There is some static current there. Is there any better method?
