Abstract
A power circuit for a power amplifier which operates in an inactive period and an active period is provided and includes a power supply unit, a current limiting unit, a storage unit, and a converting unit. The power supply unit provides a first current. The current limiting unit is arranged to process the first current to generate a second current. The storage unit is arranged to provide a storage voltage. The storage unit is charged by the second current during the inactive period and discharged by a third current during the active period. The converting unit provides an active power to the power amplifier according to the storage voltage, the second current, and the third current during the active period.
