Abstract

Recently Li and Tsividis (IEEE Trans. Circuits and Sys. II, vol. 47, no. 3, pp. 169-175, 2000) introduced a novel loss control feedback loop for VCO indirect tuning of RF integrated filters, because conventional loss-control loops were not able to render stable amplitude control for high frequency applications. In this paper, we show a slight modification to the classical control loop, rendering stable control. Results are validated through device level simulations
