Abstract

PURPOSE:To decrease the voltage fluctuation and the ripple by installing the oscillator featuring several units of oscillation output of different phases plus the charge pump circuit featuring several input. CONSTITUTION:Oscillator part A comprises the oscillation circuit consisting of capacitors C1 and C2, resistances Q1 and Q4 composed of the equivalent transistors plus each inverter of transistors Q2,Q3, and Q5,Q6 and Q7,Q8 each and the driving circuit comprising transistors Q9-Q14, Q17 and Q18 respectively. Thus the oscillation output featuring the opposite phases to each other are obtained at output terminals O3 and O4. The double-input charge pump circuit consists of the two sets of circuits comprising capacitor C3, transistors Q15 and Q16, capacitor C4 plus transistors Q19 and Q20 each. And the charge pump charges twice load capacitor C5 alternately in one cycle of the oscillator's oscillation, and as a result the cycle charging C5 can be reduced down to 1/2 oscillation cycle.
