Integrated Frontend Analog Circuits for MEMS Sensors: in Ultrasound Imaging and Optical Grating Based Microphone,Used
Delivery time: 8-12 business days (International)
Microscaling makes MEMS sense capacitance small in a CMUT array element for intravascular ultrasound imaging. Smaller sensors lead to a lower activeto parasitic ratio and thus, degrades sensitivity. Here capacitive feedback charge amplifier is shown as an alternative approach to resistive feedback amplifier. Capacitive feedback charge amplifier provides high sensitivity, small area, low distortion and power saving. This approach of charge amplifiers is also suitable in capacitive microphones where it provides low power and high sensitivity. In the case of biomimetic microphone structure, optical detection overcomes capacitive detection's thermal noise issues. Also with microscaling, optical detection overcomes the increased parasitics without any sensitivity degradation, unlike capacitive detection. For hearing aids, along with sensitivity, battery life is another challenge. We propose the use of 1 bit frontend sigmadelta ADC for overall improved hearing aid power efficiency. Frontend interface based on envelope detection and synchronous detection have also been designed. Circuit techniques are used for maximizing signal handling with low supplies.
By changing our most important processes and
products, we have already made a big leap forward. This ranges from the
increased use of more sustainable fibers to the use of more
environmentally friendly printing processes to the development of
efficient waste management in our value chain.
