CONTROL SIGNAL GENERATION CIRCUIT, CHARGE PUMP DRIVE CIRCUIT, CLOCK DRIVER, AND DRIVE METHOD OF CHARGE PUMP |
摘要 |
A control signal generation circuit which generates a control signal for controlling a gate of an MOS transistor, comprises a first switching part connected to a current source and the gate and controlled based on an input signal; and a second switching part connected to the current source and the gate and controlled based on an input signal and control signal, wherein a voltage value of the control signal changes based on the input signal, and a slant of the voltage value with respect to time is switched to become smaller after the voltage value exceeds a threshold voltage of the MOS transistor compared with when the voltage value equals to or less than the threshold voltage of the MOS transistor. |
