Abstract
Embodiments of the present invention provide a voltage level shifter used to translate a binary input signal representing a binary sequence to a binary output signal representing the same binary sequence. The input signal is provided by an input voltage varying between a first input voltage level and a second input voltage level. The output signal is provided by an output voltage varying between a first output voltage level and a second output voltage level. The output signal has a delay relative to the input signal, and the voltage level shifter has a leakage current. The voltage level shifter has a first operating mode and a second operating mode. In the second operating mode, the delay is shorter while the leakage current is higher than in the first operating mode.
