Abstract:
A drive voltage generating circuit which has a first shifter receiving an input voltage and outputting a first drive voltage obtained by first shifting a voltage level of the input voltage; a second shifter receiving outputting the second drive voltage obtained by second shifting a voltage level of the first drive voltage; and a drive voltage controller adjusting one of a shifting amount of the first shifter and a shifting amount of the second shifter in accordance with a surrounding temperature, wherein the second drive voltage is continuously varied in an analog manner, in accordance with the surrounding temperature.
