Input voltage is Vi, and output voltage is Vo.Clock signal CK_b is the inversion signal of clock signal CK, it is only necessary to
CK signal phase inverters do one it is anti-phase just can be with, it is not necessary to processed with complicated circuit.If initial voltage is VDD, when CK is from 0
When volt jumps to VDD；Node J1 also can jump to 2VDD from VDD, and node Z1 can be from 0 saltus step into 2VDD.When CK is jumped to from VDD
When 0, node J1 jumps to VDD from 2VDD, and node Z1 jumps to 0 from 2VDD.The lower section of follow-up per grade node Jn main circuits is all
Coupled with CK (or CK_b) by an electric capacity, the effect of this electric capacity is also to realize the width Jn voltages one VDD of lifting
Degree.It can be seen that the voltage for finding out node Yn (n is natural number) is to addition of one on the basis of correspondence Zn (n is natural number)

VDD, that is, realize the lifting of node J (n+1) voltage magnitude.And so on, the voltage of node J (n+1) always compares previous stage
The high VDD of node Jn amplitude.Last output Vo can be in the presence of output load capacitance the section of one-level above
The voltage of point Jn is steady to filtering, is relatively stable amplitude V (Jn), which achieves the purpose that voltage is raised step by step, finally
Realize the function of charge pump.
