Abstract

The invention provides a power amplifier and a power control method. The power amplifier comprises a cascaded pre-stage circuit and a cascaded driving stage of the power amplifier; a biasing circuit for providing a biasing voltage to a controllable amplification stage; and a controllable amplification stage connected with the biasing circuit and the output end of the cascaded riving stage, whereinthe controllable amplification stage comprises a power amplification module, the power of an output signal is controlled by adjusting the number of power amplification modules, and binary on-off keying modulation is realized by adjusting switching-on and switching-off operations acting on the biasing voltage of the power amplification modules. According to the power amplifier and the power control method, three output power control schemes are realized, the speed of a signal switch in an OOK modulation mode is controlled flexibly, power loss caused by temperature rise is compensated by the optimized biasing circuit, circuits of the invention are realized by adopting a CMOS technology and can be integrated in an SoC system conveniently.

Description

technical field [0001] The invention relates to the field of integrated circuits, in particular to a power amplifier and a power control method thereof. Background technique [0002] The power amplifier is the key module of the transmitter. It is located at the back end of the transmitter. It is generally used in wireless communication systems to amplify the modulated signal to a certain output power and send it to the antenna for transmission. [0003] The rapid development of the wireless communication market continues to promote the development of transceivers in the direction of high integration, low power consumption, and low cost. Therefore, more and more chips are designed and implemented using cheap and relatively mature and reliable CMOS technology. In order to obtain better performance, traditional power amplifiers are mostly designed and realized by GaAs and other processes, which makes it difficult to integrate the power amplifier with other CMOS circuits, which ...
