ABSTRACT:
A charge pump type booster circuit generates a positive or negative boosted output voltage by switching booster paths one by one. This charge pump type booster circuit includes a plurality of booster paths, each of the plurality of booster paths including at least one booster capacitor, wherein a number of the booster capacitor at each of the plurality of booster paths is different between one booster path and the other booster path. This makes it possible to suppress an increase in a number of an external capacitor for setting an output voltage of the booster circuit constant.
