Abstract
In a bias voltage generating circuit for outputting through switching over a plurality of bias voltages and standby voltages provided for the respective bias voltages, a voltage return unit is provided for each bias voltage, and charges stored in the voltage return unit are supplied before power ON starts so that the bias voltage is approximated to a predetermined voltage. A drive controller drives the voltage return unit and a standby voltage generator, and a period of driving control is arbitrarily set by a register.
