POWER CIRCUIT AND METHOD THEREOF

摘要

A power circuit and a method thereof are provided. The method includes: determining, by a power controller, a first signal is to be transmitted in the continuous mode or the burst mode; when the first signal is to be transmitted in the continuous mode, activating, by a power controller, a continuous mode converter; when activated, converting, by the continuous mode converter, a first voltage down to a second voltage and supplying the second voltage to the first power amplifier; when the first signal is to be transmitted in the burst mode, activating, by a power controller, a burst mode converter; when activated and the first power amplifier is inactive, receiving, by a burst mode converter, a first current to accumulate a burst energy; and when activated and the first power amplifier is active, supplying, by the burst mode converter, the burst energy to the first power amplifier.

主权项

1. A power circuit, providing powers to a first power amplifier operating in a continuous mode or in a burst mode, connected to a power supply supplying a first voltage and a first current, comprising:
a continuous mode converter, when activated, configured to convert the first voltage down to a second voltage; a burst mode converter, when activated, configured to receive the first current to accumulate a burst energy when the first power amplifier is inactive, and supply the burst energy to the first power amplifier when the first power amplifier is active; and a power controller, configured to determine a first signal is to be transmitted in the continuous mode or the burst mode, when the first signal is to be transmitted in the continuous mode, activate the continuous mode converter to apply the second voltage to the first power amplifier to transmit the first signal, and when the first signal is to be transmitted in the burst mode, activate the burst mode converter to provide the burst energy to the first power amplifier to transmit the first signal.
