HIGH VOLTAGE GENERATING CIRCUIT OF SEMICONDCUTOR DEVICE

摘要

The device reduces the threshold voltage loss of the clamping device and charge transfer device and improves the effectiveness. The device includes: the 1st clamping means (51) for inputting the 3rd oscillating signal (&phgr;osc23) from an oscillating signal generator; the 2nd clamping means (52) for inputting the 4th oscillating signal (&phgr;osc24); the 1st charging pumping means (53) for inputting the 2nd oscillating signal (&phgr;osc22); the 2nd charge pumping means (54) for inputting the 1st oscillating signal (&phgr;osc21) and the charge transfer means (55) for connecting the input to the output of the charge pumping means (53,54) and clamping means (51,52).
