Abstract
A power detection circuit () having a temperature compensation function, and a radio-frequency front-end module comprising the power detection circuit. The power detection circuit () comprises at least one Stage of power detection unit (Stage, Stage, Stage) and an integration unit (Sum), wherein an input end of the integration unit (Sum) is connected to an output end of the power detection unit (Stage, Stage, Stage); a resistor which is connected to a bias voltage in the power detection unit (Stage, Stage, Stage) is a thermistor, and/or a resistor which is connected to a reference ground potential in the integration unit (Sum) is a thermistor. The technical problem of requiring a plurality of bias voltages (Vreg) with different temperature coefficients to supply power due to different circuit modules having different requirements for temperature coefficients of bias voltages (Vreg) is solved.
