Abstract:
A boosting circuit includes a charge pump circuit; and a power supply circuit configured to supply a power supply voltage to the charge pump circuit. The power supply circuit includes an N-channel transistor connected with a power supply terminal of the charge pump circuit; and a current control circuit configured to control current flowing between the N-channel transistor and the charge pump circuit through the power supply terminal.
