Abstract

The invention discloses a power supply and a power supply voltage regulation method. The power supply comprises: a current source device, a voltage source device and a voltage selection device, wherein the current source device is used to provide a current signal to the voltage source device; the voltage source device is connected to To the current source device, including multiple voltage sources, for converting the current signal from the current source device into a voltage signal; the voltage selection device, connected to the voltage source device, for selecting one of the voltage signals from the multiple voltage sources as the output voltage signal. Through the present invention, one current source device is used to supply power to multiple voltage sources in the voltage source device respectively to maintain the stability of the output voltage (V1~VN) of each voltage source, and the voltage selection device selects one of the voltages according to the actual voltage regulation requirements The output of the source is used as the final output voltage (Vout), which can greatly simplify the structure of the multi-channel input power supply, thereby reducing the volume of the power supply, reducing the cost and improving the efficiency.

Description

technical field [0001] The present invention relates to the communication field, in particular to a power supply and a power supply voltage regulation method. Background technique [0002] In electronic devices, in order to minimize energy consumption, there are many occasions that require the power supply to have a fast voltage regulation function, such as the central processing unit (Central Processing Unit, referred to as CPU) power supply, the power supply of the radio frequency power amplifier, etc., among which More typical is the power supply device of the radio frequency power amplifier. [0003] In order to cope with the continuous improvement of users' demand for bandwidth, the modulation methods of communication systems have become more and more complex. One of the prominent problems brought about is the low efficiency of RF power amplifiers, which has become a bottleneck for improving the efficiency of the entire communication system. For a linear power amplifie...
