Abstract
The present invention relates to a power detection circuit and an RF signal amplification circuit having the same. According to an embodiment of the present invention, a power detection circuit including a coupling unit adjacent to an RF matching inductor to extract induced power; a rectification unit for rectifying the signal output from the coupling unit to output the rectified signal; a slope adjustment unit connected between an output terminal of the rectification unit and a ground and adjusting a voltage slope for power detection by changing the output signal of the output terminal of the rectification unit according to changes in internal impedance; and a smoothing unit for receiving the output signal of the output terminal of the rectification unit to smooth the received signal into a DC voltage for power detection using the voltage slope is provided. Further, an RF signal amplification circuit having the same is provided.
