Abstract
Electric charge transmit elements (QD) transmit electric charge from a terminal side (NA) to a control electrode side (NB) of the circuit. The voltage at the control electrode side (NB) is raised by a capacitor configuration (CB). Voltage stabilizing elements (QC) are connected in parallel to the electric charge transmit elements between the terminal side and the control electrode side. In transferring the electric charge from the control electrode side (NB) to the other terminal side (NC), the voltage at the control electrode side (NB) is kept higher than the other terminal side (NC). Therefore, because loss of voltage by the electric charge transfer elements (QB) in transferring the electric charge is eliminated, a predetermined voltage is obtained efficiently in a short time, and a highly reliable booster circuit is provided.
