Résumé

This paper focuses on the design of high-performance Coupled Slow-wave CoPlanar Waveguide (CS-CPW) in CMOS technologies for the mm-wave frequency bands. First, the theory as well as the electrical model of the CS-CPW are presented. Next, the analytical approach for the calculation of the model parameters is discussed. Then, by using the developed model, two millimeter-wave backward directional 3-dB couplers are designed in a Bipolar Complementary-Metal-Oxide-Semiconductor (BiCMOS) 55-nm technology for 120 and 185-GHz operation, respectively. Simulation and experimental results demonstrate that the use of the CS-CPW concept leads to state-of-the-art performance, with a good agreement between the analytical model, electromagnetic simulations and measurement results.
