Abstract
A boosting circuit of charge pump type includes: charging portion for applying an input voltage to a first capacitor; double boosting portion for applying the input voltage to a second capacitor and applying a sum of the input voltage and a voltage across the first capacitor to an output capacitor in a first predetermined period after start of a boosting operation; and triple boosting portion for repeating in order, after end of the first predetermined period, a step of applying the sum of the input voltage and the voltage across the first capacitor to the second capacitor and a step of applying a sum of the voltage across the first capacitor and a voltage across the second capacitor to the output capacitor.
