Abstract:This paper describes an intelligent stent for Pulmonary Artery Restenosis (PAS) monitoring, comprising MEMS pressure sensors and CMOS electronics. First, a novel MEMS sensor design tool is described and some fabricated PolyMUMPs devices are presented. Then, a proposed low-power analog system for monitoring intelligent stents is analyzed. This architecture is fully-integrated and can be divided into four basic blocks: voltage rectifier, voltage reference, mode-selector and oscillator. The integrated circuit (IC) has been fabricated in TSMC 0.18 μm CMOS technology. Post-layout simulation results show average power consumptions of 152.1 μW and 547.1 μW in idle and active states, respectively
