In this paper, we propose to design a 60 GHz antenna using a CMOS 130 nm bulk process. The chosen antenna is a dipole with meandered arms to minimize the occupied space on the chip. With a simulated matching bandwidth of 11% (|S11| less than -10 dB), this antenna operates in the available bandwidth around 60 GHz which is of particular interest for Wireless Personal Area Network (WPAN) applications...
This paper presents the design methodology, simulation and measurement results of a CMOS 12 GHz rotary travelling wave voltage controlled oscillator. The different simulations (electrical using SPICE and electromagnetical using HFSS) are presented. These results are compared to a theoretical approach and measurements. The oscillator has been fabricated in a 0.13 mum RF-CMOS technology. The phase noise...
This paper proposes a complete solution for the design and modeling of a switched-capacitor rotary traveling wave voltage controlled oscillator. The main point of the proposed methodology is to get a unique simulation and modeling environment, so we have focused on EDA tools interoperability. As a result, we get a complete flow for a 14.35 GHz VCO design and bottom-up verification, starting from electromagnetic...
This paper shows the feasibility of combining rotary traveling wave (RTW) oscillator and frequency switch tuning compensation based on a capacitor network to achieve a temperature and process variations robustness of voltage controlled oscillators (VCO). This concept has been proved by combining transistor level simulations for the active part and electromagnetic simulations for the transmission lines...
