Abstract
A booster circuit is provided with first and second booster circuit sections, which have the same construction and each of which is provided with capacitors and transistors for controlling the gate voltage of each of the final stage output transistor. The output terminals of the first and second booster circuit sections are connected to each other. Input pulses F1 to F4 are inputted to positions of first and second booster circuit sections, respectively. Input positions of F2 are replaced with those of F4 between the first and second raising circuit sections. Likewise, input positions of F1 are replaced with those of F3 therebetween. As a result, the first and second booster circuit sections operate, while having phases opposite each other. The booster circuit thus provides less voltage loss, smoother output voltage and a higher voltage raising capability.
