ABSTRACT:
A circuit for generating an output voltage which is used during active time periods and not during inactive time periods. A DC/DC converter converts an input voltage to the output voltage. During the inactive time periods, a capacitor is charged with a quantity of charge which is then used to generate the output voltage during the active time periods. The quantity of charge is generated by a current from a current generator. The current is lead to the ground via the capacitor and a diode. As the capacitor is charged more and more, the current diminishes to zero. A control voltage switches the circuit during the active time periods so that the output voltage is obtained. The circuit can be used in a radio transmitter for portable radio equipment, in which the radio equipment is used in a radio system where transmissions occur in bursts.
