Abstract:
A level shift circuit is configured to receive reference voltage and first to third voltages, and to generate an output signal. The voltages satisfy a condition in which the reference voltage the first voltage>the second voltage>the third voltage. The level shift circuit includes a first level shift circuit configured to receive a first signal having a first amplitude within a difference between the reference and first voltages, and level shift the first signal to a second signal having a second amplitude within a difference between the reference and second voltages, and a second level shift circuit configured to level shift the second signal to a third signal having a third amplitude within a difference between the reference and third voltages, and output the third signal as the output signal.
