Abstract
A novel active-inductor based VCO design, employing a 180 nm TSMC technology, is postulated in this work. The coarse frequency is obtained in this VCO system by regulating the MOS-based active inductor. This design provides a high oscillation frequency of 3.7 GHz and a tuning range of 99.25% when the voltage ranges from 1 to 2 V. The total power consumed by this active-inductor based VCO varies from 0.7 mW to 33.32 mW within the specified range. The achieved phase noise is − 107 dBc/Hz at 1 MHz offset frequency. The figure of merit measured is − 162.15 dBc/Hz. The results demonstrate that the proposed VCO functions more effectively than the existing VCOs.
期刊介绍：
Analog Integrated Circuits and Signal Processing is an archival peer reviewed journal dedicated to the design and application of analog, radio frequency (RF), and mixed signal integrated circuits (ICs) as well as signal processing circuits and systems. It features both new research results and tutorial views and reflects the large volume of cutting-edge research activity in the worldwide field today.
A partial list of topics includes analog and mixed signal interface circuits and systems; analog and RFIC design; data converters; active-RC, switched-capacitor, and continuous-time integrated filters; mixed analog/digital VLSI systems; wireless radio transceivers; clock and data recovery circuits; and high speed optoelectronic circuits and systems.
