Problems solved by technology

[0002] At present, the power amplifier in the power amplifier circuit is often damaged because the power components in the power amplifier are not working in the safe operating area. In the prior art, most of the current output by the power amplifier is monitored through overcurrent protection. When the output current of the amplifier exceeds the threshold value, the overcurrent protection will perform an action to protect the power amplifier circuit, but

Abstract

The invention discloses a power amplifier monitoring method and a power amplification circuit, and the method comprises the steps: collecting an analog voltage group and an analog current group of a power amplifier in real time through a collection module, and transmitting the analog voltage group and the analog current group to a conversion module; performing voltage analog-to-digital conversion on the analog voltage group through a conversion module to obtain a digital voltage group, performing current analog-to-digital conversion on the analog current group to obtain a digital current group, and transmitting the digital voltage group and the digital current group to a monitoring module; the monitoring module outputs the working parameters of the digital voltage group and the digital current group to obtain the parameter group and judges the threshold values of the working parameters in the parameter group to obtain the monitoring result, and the monitoring result shows whether the power amplifier works in the safe area or not. The working state of the power amplifier is accurately monitored, and the performance of the power amplifier is fully utilized.

Description

technical field [0001] The invention relates to semiconductor technology, in particular to a power amplifier monitoring method and a power amplifier circuit. Background technique [0002] At present, the power amplifier in the power amplifier circuit is often damaged because the power components in the power amplifier are not working in the safe operating area. In the prior art, most of the current output by the power amplifier is monitored through overcurrent protection. When the output current of the amplifier exceeds the threshold value, the overcurrent protection will perform an action to protect the power amplifier circuit, but because the maximum current allowed to work in the safe working area is not constant, it will be affected by other variables of the power component, resulting in the output current of the power amplifier When the threshold value is exceeded but the working state still in the safe working area cannot be utilized, therefore, the working state of th...
