Design and analysis of integrated Built-in-Sensors for wireless reconfigurable applications

In this paper design, analysis and fabrication of On-Chip Built-in-Sensors for wireless reconfigurable applications are presented. Feasibility of On-Chip Built-in-Sensors is investigated through realization of scalable LNA gain. The scalability of the LNA gain is digitally controlled by attenuators (implemented using two options: MOS and Bipolar switches). Novel automatic oscillation amplitude control of VCO-PLL systems implemented as Built-in-Self-Sensor is proposed. The Built-in-Sensor circuits are realized using NXP SiGe:C technology and characterized based on careful correlation between predicted simulation results and experimental verifications.
