International audience. In this paper, the slow-wave coplanar stripline (S-CPS) technology is utilised to design high performance and small footprint resonators operating within the millimetre-wave band from 50 to 80 GHz. The proposed resonators are designed based on high quality factor quasi-lumped capacitances and inductances offering a great flexibility in terms of design. The derivation of these components from the S-CPS is explained theoretically and their behaviour is validated by EM simulation; an equivalent electrical model is also developed. The proposed concepts are demonstrated in the BiCMOS 55-nm technology, and a good agreement between modelling, EM simulation and measurement results is achieved. The proposed devices could later be considered as interesting elementary blocks for the design of mm-wave filters.
