A few upconversion mechanisms are not fully understood yet. In particular, in class-B CMOS oscillators, the reason why a large tail capacitance combined with transistors entering the triode region for a portion of the oscillation cycle dramatically amplifies the 1/f noise upconversion has not been clearly pinpointed. This work introduces a simple yet powerful model to fully capture the 1/f noise upconversion mechanism. It shows that when the transistors enter the triode region, charge sharing between the tail capacitance and the tank capacitance injects a noise charge into the tank, generating phase noise perturbations quantified by the impulse sensitivity function. The analytical description results in closed-form equations that predict the $1/f^3$ phase noise sideband accurately, without relying on complex harmonic analysis or specific device nonlinearities. The excellent agreement with simulations performed both using idealized and real 55nm CMOS transistor models confirms the validity and robustness of the proposed framework, offering new insights and practical design guidelines for low phase noise CMOS oscillators.</style></abstract></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Bevilacqua, A.</style></author><author><style face="normal" font="default" size="100%">Mazzanti, Andrea</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Analysis of CMRR in Doubly-Tuned Transformer Baluns</style></title><secondary-title><style face="normal" font="default" size="100%">IEEE Transactions on Circuits and Systems II: Express Briefs</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">balun</style></keyword><keyword><style  face="normal" font="default" size="100%">baluns</style></keyword><keyword><style  face="normal" font="default" size="100%">Circuits</style></keyword><keyword><style  face="normal" font="default" size="100%">Doubly-tuned networks</style></keyword><keyword><style  face="normal" font="default" size="100%">Equivalent circuits</style></keyword><keyword><style  face="normal" font="default" size="100%">Impedance</style></keyword><keyword><style  face="normal" font="default" size="100%">Integrated circuit modeling</style></keyword><keyword><style  face="normal" font="default" size="100%">transformers</style></keyword><keyword><style  face="normal" font="default" size="100%">Voltage</style></keyword><keyword><style  face="normal" font="default" size="100%">Windings</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2024</style></year></dates><volume><style face="normal" font="default" size="100%">71</style></volume><pages><style face="normal" font="default" size="100%">4874-4878</style></pages><language><style face="normal" font="default" size="100%">eng</style></language></record></records></xml>
