Abstract :
This paper presents the analysis, design and implementation of a millimeter-wave W-band power detector. Fabricated in a 0.18-μm SiGe BiCMOS technology, the detector circuit exhibits a responsivity of 91 kV/W, a noise equivalent power of 0.5 pW/Hz1/2, and a noise figure of 29 dB. The power dissipation of the detector is 75 μW. Reasonable agreement between simulations and measurements is obtained. To the authors´ best knowledge, the detector in this work achieves the highest responsivity reported to date for any solid-state W-band detector.
