VOLTAGE CONVERSION CIRCUIT AND SEMICONDUCTOR INTEGRATED CIRCUIT DEVICE PROVIDED WITH IT |
摘要 |
A voltage conversion circuit which uses first delay circuit for delaying a specified time a reference pulse signal having a constant pulse width and a second delay circuit for delaying an arbitrary time an output signal from the first delay circuit to thereby generate a variable-pulse-frequency output pulse signal and change an output voltage according to the pulse frequency of the output pulse signal
