Abstract:
1. A semiconductor device comprising: an antenna portion configured to receive a radio wave from outside; a rectifier circuit portion configured to rectify an output of the antenna portion and configured to output a direct current voltage, the output of the rectifier circuit portion being used as a first power supply potential; a regulator circuit configured to receive an output of the rectifier circuit portion and configured to output a specific voltage, the output of the regulator circuit being used as a second power supply potential; a booster circuit configured to receive the output of the rectifier circuit portion and configured to boost the first power supply potential; a memory configured to receive the output of the regulator circuit; a clock generation circuit, into which the second power supply potential is input, and which is configured to generate clocks for the booster circuit; and a level shifter, into which the first power supply potential and an output of the clock generation circuit are input, and which is configured to amplify the output of the clock generation circuit and configured to output the amplified output of the clock generation circuit as a clock of the booster circuit.
