OUTPUT CIRCUIT OF DRIVING IC OF CCD TYPE

摘要

a level shifting circuit (LSC) for shifting the voltage level of the input pulses to drive a charge coupling device (C1); a p type MOS transistor (MP) and an n type MOS transistor (MN) for outputting pulses through a common drain to drive the charge coupling device (C1); and a complementing type push- pull inverter connected to the MOS transistors. The ratio of the W/L value of the p type MOS transistor (MP) to that of the n type MOS transistor MN is at least 3:1.
