SWITCHING CONTROL CIRCUIT AND WIRELESS COMMUNICATION DEVICE |
摘要 |
A switching control circuit includes a level shifter that generates a switching control signal for a switching circuit, and a voltage generation circuit. The voltage generation circuit includes a first oscillator that generates a first oscillating signal, a frequency spectrum of which is controlled to be spread spectrum based on a second oscillating signal different from the first oscillating signal, and a power supply circuit that generates a power supply voltage based on the first oscillating signal and supplies a converted power supply voltage to the level shifter. |

1. A switching control circuit comprising:
a level shifter configured to generate a switching control signal for a switching circuit; and a voltage generation circuit that includes a first oscillator configured to generate a first oscillating signal, wherein a frequency spectrum of the first oscillating signal is subjected to spread spectrum based on a second oscillating signal different from the first oscillating signal; and a power supply circuit configured to generate a power supply voltage based on the first oscillating signal, and supply a converted power supply voltage to the level shifter. |
