• A CMOS rectifier that converts 60 GHz signal to DC voltage is presented for millimeter-Wave (mm-Wave) power detection. The sensitivity of the rectifier is -27.5 dBm, which is the highest sensitivity compared with previous works. The optimization method for the rectifier is proposed considering the power matching design and loss of the passive devices at 60 GHz. According to the proposed method, the number of stage should be decreased because the stacked structure that is often used at frequency of several GHz doesn't increase the sensitivity in the case of 60 GHz. The loss of the passive devices is minimized by adopting the proposed optimization method. Additionally, the 60 GHz Wake up Receiver (WuRX) is discussed as application of the rectifier proposed in this work.
