PROBLEM TO BE SOLVED: To provide a charging pump capable more satisfactorily compensating fluctuations in a manufacture process and an operating parameter than those of a conventional pump. SOLUTION: This pump is provided with a main pump circuit 36, which employs main 1st and 2nd switching transistors(TRs) and an auxiliary pump circuit, and the charging pump applies a variable bias at least to a 1st switching TR, in response to the operation of the auxiliary pump circuit. The auxiliary pump circuit is provided separately to use the circuit as a control form and provides a signal to adjust the bias of one side of the switching TR of the major pump circuit. |
