RF CMOS Oscillators Design for autonomous Connected Objects

摘要

Voltage controlled oscillator (VCO) is an integral part of IoT wireless transceiver components. In this paper, VCOs operating around 2.4 GHz have been designed in CMOS technology. The relation between their components and specifications is studied for their performance optimization. Ultra-low power, less than 270 μW, has been obtained, while performing a frequency tuning range of about 10% between 2.1 and 2.4 GHz. Investigations on phase noise performance have been also achieved.
