ABSTRACT:
In a radio signal transmitter, a microcomputer operates by receiving an output voltage of a battery to sequentially generate a voltage boosting control signal. This voltage boosting control signal has a longer high level period as generated later. The voltage booster circuit boosts the output voltage of the battery by increasing the number of times of oscillating operations during the high level period of the voltage boosting control signal depending on the increased high level period.
