摘要:
A level shifting device comprises an input stage, a cascode stage, a cross-coupled stage, and an output stage. The input stage may receive a data signal or binary logic input in a first data range, a complement of the data signal, and a first voltage. The cascode stage may receive a first voltage and may be connected to the input stage. The cross-coupled stage may be adapted to isolate the first voltage and may be connected to the cascode stage. The output stage may receive a second voltage, provide an output, and be connected to the cross-coupled stage. The cascode stage may be adapted to provide the first voltage as the output when the logic input is a first value and provide the second voltage as the output when the logic input is a second value. Other embodiments are also claimed and described.
