This paper presents a smart sensor microphone based on silicon nanowire resistive gauge for hearing aid applications through cochlear implant. The system includes the sensor together with its bias circuit, the preconditioning stage and the digital interface that ease integration on heterogenic system. One important concern of audio field is the wide dynamic range addressed since human hear is able...
Investigation of readout electronic dedicated to electromechanical audio sensor is presented. The circuit is able of reading piezoresistive gauge implemented with silicon nanowire (NEMS) and bring electromechanical signal to high-resolution digital output. Low-noise low-power CMOS operational transconductance amplifier (OTA) is presented. The low-noise amplifier (LNA) has been designed in a 0.28 μm...
The design and implementation of a CMOS integrated analog to digital interface dedicated to hybrid integration of MEMS resistive microphone is presented. Audio sensing is achieved with an innovative low-cost technology that uses single crystal piezoresistive silicon nanowires as transducer in a MEMS. The circuit composed of a low-noise instrumentation preamplifier followed by a single bit fourth order...
