High speed digital level shifter |
摘要 |
A high-speed digital level shifter is described. The preferred embodiment shifts an input signal with a lower amplitude to a signal with a higher amplitude. The level shifter includes a signal driver circuit to drive up the input signal to a driver signal having higher voltages. The driver signal is used to drive an output circuit that generates an output signal having amplitude of a high voltage power source. The output circuit has improved performance being driven by the driver input signal. A signal stepper is added to further improve the performance by pulling up the output voltage in two stages.
