Multiple voltage domains are commonplace in modern SoCs and level shifter (LS) circuits allow different voltage domains to be interfaced with each other. As the reduced supply voltages are extensively used in digital blocks for low-power operation, the conversion of sub-threshold voltage levels to f...
