摘要： A system and method of shifting a data signal from a first voltage domain having a first logic level to a second voltage domain having a second logic level, the second logic level having a second logical high state greater than a first logical high state in the first logic level and a single power supply logic level shifter circuit having a single power supply source, an input node and an output node, the input node coupled to a sender circuit in the first voltage domain and the output node coupled to a receiver circuit in the second voltage domain, the single power supply source being coupled only to a single power grid in the second voltage domain.
