Abstract :
This paper presents the electronics for the resonance control of a resonance contact sensor. The interface consists in an analog front-end and a digital control unit, fabricated in a CMOS standard technology of 0.13 mum from STM. The sensor is a SMART multi-layer piezo-polymer micro-cantilever working in resonance mode. The sensing is done using an electrical isolated piezo-layer of the microstructure. For the design of the electronics an electrical model of the sensor has been developed. The model is described in detail in the paper.
