<P>PROBLEM TO BE SOLVED: To achieve easy and appropriate FET on-off control. <P>SOLUTION: A charge pump circuit 1 includes: a FET 103 (104) used as a charging/discharging switch of a capacitor C1; a detection section 109 (110) that generates a detection signal S11 (S12) on the basis of a current passing through the FET 103 (104) or a voltage across the FET 103 (104); and a drive section 107 (108) that generates a drive signal G11 (G12) of the FET 103 (104) according to the detection signal S11 (S12). <P>COPYRIGHT: (C)2013,JPO&INPIT |
