Hi, everyone,

How can I design a shifter with multivoltage?
In my project, there are 5 voltage(1.0v, 1.2v, 1.5v, 1.8v,2.5v) running,
How can they communicate?

multivoltage domain

you may contact your foundry, the technology library provided by the Foudry ought include the shifter cell with converting the signal.

Re: multivoltage domain

You mean level shifter, you need to go to analog design forum to ask the question.

Re: multivoltage domain

IC technology is continuing to scale according to Moore’s
Law, with the overall chip circuit requirements driving the
MOSFET device and process integration requirements and
optimal choices.

In the 2001 ITRS the driver for the high
performance logic is maximizing MOSFET intrinsic speed,
while the driver for low power logic is minimizing
MOSFET leakage current. The rapid increase in off state
sub-threshold leakage and gate tunneling currents due to
device scaling for more performance may be controlled by
utilizing multi Vt and multi gate oxide transistors and by
utilizing device/design/architectural techniques such as well
biasing and power down/reduction.
