Abstract

This paper presents a RMS power detector in 65 nm CMOS for applications in WPAN 60 GHz band. After presenting the context, the interest of power detection in RF transmitter chain is explained together with some 60 GHz VSWR antenna measurements. Then, a state of the art of the detection techniques is given to justify our architecture choice and the operating principle is detailed. Finally, simulations results are presented which show a linear detection range of 25 dB at 60 GHz.
