Abstract

A device for tracking power supply and controlling method thereof are provided, the device includes: a signal generator, a working voltage source (116-1), a tracking voltage source (117) and a current source (118). The working voltage source (116-1) provides the first bias voltage and the corresponding power to the tracking voltage source (117). The signal generator sends input signal to the tracking voltage source (117), and sends a current adjusting signal to the current source (118). The tracking voltage source (117) amplifies the input signal according to the first bias voltage provided by the working voltage source (116-1). The current source (118) outputs the current and the corresponding power according to the current adjusting signal, and produces supply voltage and power for a radio frequency power amplifier according to the amplified input signal output from the tracking voltage source (117) and the current and the corresponding power output from the current source (118), wherein the tracking voltage source (117) is connected in parallel with the current source (118).

Description

technical field [0001] The invention relates to the field of power supply control, in particular to a tracking power supply device and a control method. Background technique [0002] In modern wireless communication technology, there is a technology to change the drain voltage of the RF power amplifier. This technology can quickly adjust the drain voltage of the power amplifier tube according to the requirements of the system. The adjustment range can reach tens of volts, and the adjustment time is <100 Nanoseconds, and ensure high adjustment accuracy. This technology can make the wireless power amplifier in a high efficiency state without losing the radio frequency index during operation, especially suitable for the situation where the ratio of peak power to average power is large, thereby greatly reducing the energy consumption of the radio frequency power amplifier. [0003] Although the current voltage regulating power devices such as linear voltage regulators can en...
