Design and Investigation of Low-Power Linear-In-Decibel S-Band Power Detector

This research aims to design a low-power linear-in-decibel RF power detector using a 180 nm standard CMOS process. The RF power detector targets S-band frequency range (2 GHz to 4 GHz) applications in wireless communication and as sensing devices in the agriculture sector, where low-power consumption, wide dynamic range, and high sensitivity are required. The S-band frequency is suitable because most design of microwave ring resonators for agricultural applications operates in frequency ranging between 2 GHz and 4 GHz. The proposed power detector could also be used to manufacture cheaper VNA's which has multiple important applications at present time.
