초록

In this paper, High Q Inductor using negative resistance circuit and the ceramic inductor was designed and fabricated at 2GHz. It was Improved the inductor of Q=90 using a inductor with Q=30 added to negative resistance circuit at 2GHz. As a result, at the bias condition of 3V and 16mA, the output power and phase noise in the operation frequency 2.01GHz are 5dBm and -115.34dBc/Hz at 100kHz offset from carrier, respectively. Phase noise was improved -10dBc/Hz at 100kHz offset compared to only using ceremic inductor.
