Current-reuse RF LC-VCO Design for Autonomous Connected Objects

In this paper, a fully integrated sub-mW current-reuse LC voltage controlled oscillator (VCO) is presented. It is designed by following a design methodology to find the optimal parameters lowering the power consumption. The implemented LC-VCO is successfully demonstrated through its silicon prototype in 130nm CMOS technology. It consumes only $262{\mu} \mathrm{W}$ from 1V supply voltage making it suitable for autonomous connected objects and IoT applications.
