ABSTRACT:
A boost circuit includes: level shifters3and4for shifting a high level of a clock signal; a first boost means which contains transistors QP3and QP4for conducting switching in accordance with the clock signal whose high level has been shifted and capacitors C1and C2and, thereby, generates a power source potential VDC2by conducting a charge pump operation; level shifters1and2for shifting a high level of a clock signal; inverters IV41to IV52for shifting a low level of the clock signal whose high level has been shifted; and a second boost means which contains transistors QP1and QP2for conducting the switching in accordance with the clock signal whose high level and low level have been shifted and capacitors C3and C4and, thereby, generates a power source potential VDC3by conducting the charge pump operation.
