Abstract

PURPOSE:To lead continuously charge out from a substrate by using a multiphase oscillator and then by connecting several different phase output terminals to the substrate via charge pump circuits. CONSTITUTION:Outputs extracted from respective inverters of link oscillator MPOSC composed of inverters of transistors Q11 and Q12, Q21 and Q21... Qn1 and Qn2 have constant phase difference (pi) one another. Those multiphase outputs 1-n are led to substrate SUB via charge pump circuits CP1-CPn. Therefore, since some phases among outputs of multiphase oscillator MPOSC are at a negative potential and the remainder is at a positive potential without fail during periods T1- Tn, the absorption of positive charge from the substrate via charge pump circuits CP1-CPn and the exhaustion of the charge to a power line are continued without interruption.
