Abstract
A power control circuit includes a negative feedback loop, and a radio frequency signal path including a first NMOS transistor having a gate configured as a radio frequency signal input end, a drain connected with a source of a second NMOS transistor, and a source connected with a ground terminal. A drain of the second NMOS transistor is configured as a radio frequency signal output end and connected with a first voltage source. The negative feedback loop includes a third NMOS transistor having a gate connected with an output end of a differential amplifier, a source connected with the ground terminal, and a drain connected with a source of a fourth NMOS transistor having a gate connected with a reverse input end of the differential amplifier and with a second voltage source, and a drain connected with a forward input end and a first bias current source.
