In particular, it shows how, through an advanced small-signal circuit model, to carry out an accurate and reliable design at high frequency (over 10 GHz) in modern nanoscale CMOS process. First, it reports an effective design methodology for the implementation of high-frequency CMOS AIs with a high-quality factor. This paper deals with these two open issues for a high-frequency CMOS AI characterized by high-quality factor, low-power consumption, and low noise.
The potential of active inductors (AIs) has been often reduced by lack of accurate design methodologies and limitations due to the inherent noise sources. After-wards both the device equivalent circuit and the layout are ready to be imported in the Cadence environment.

With the present software suite the complete design time is reduced significantly (typically 1 hour on a PC based on Intel® Pentium® Dual 1.80 GHz CPU with 2-GB RAM). It draws the inductor (transformer) layers for the specific process de-sign kit, including vias and underpasses, with or without patterned ground shield, and launches the electromagnetic simulations, achieving effective design automation with respect to the traditional design flow for RFICs. In detail, MIDAS allows the designer to derive a preliminary sizing of the inductor (transformer) on the bases of the design entries (specifications). In this work we present an auxiliary CAD tool for Microwave Inductor (and transformer) Design Automation on Silicon (MIDAS) that exploits commercial simulators and allows the imple-mentation of an automatic design flow, including three-dimensional layout editing and electromagnetic simula-tions. The design of modern radiofrequency integrated circuits on silicon operating at microwave and millimeter-waves requires the integration of several spiral inductors and transformers that are not commonly available in the process design-kits of the technologies.
