A MEMS Capacitive Microphone Modelling for Integrated Circuits
In this paper, a model for MEMS capacitive microphone is presented for integrated circuits. The microphone has a diaphragm thickness of 1 μm, 0.5 × 0.5 mm2 dimension, and an air gap of 1.0 μm. Using the analytical and simulation results, the important features of MEMS capacitive microphone such as pull-in voltage and sensitivity are obtained 3.8v and 6.916 mV/Pa, respectively while there is no...
متن کاملFabrication and Characterization of a New MEMS Capacitive Microphone using Perforated Diaphragm
In this paper, a novel single-chip MEMS capacitive microphone is presented. The novelties of this method relies on the moveable aluminum (Al) diaphragm positioned over the backplate electrode, where the diaphragm includes a plurality of holes to allow the air in the gap between the electrode and diaphragm to escape and thus reduce acoustical damping in the microphone. Spin-on-glass (SOG) was us...
متن کاملA 16-channel Analog VLSI Processor for Bionic Ears and Speech-Recognition Front Ends
We describe a 470pW 16-channel analog VLSI processor for bionic ears (cochlear implants) and portable speechrecognition front ends. The power consumption of the processor is kept at low levels through the use of subthreshold CMOS technology. Each channel is composed of a programmable bandpass filter, an envelope detector, and a logarithmic dual-slope analog-to-digital converter that currently o...
متن کامل6.2 GHz 0.5 mW two-dimensional oscillator array-based injection-locked frequency divider in 0.18 μm CMOS
ELECT A new two-dimensional oscillator array-based injection-locked frequency divider is proposed. Instead of using the conventional analogue tuning technique or the one-dimensional delay chain, a two-dimensional array is implemented to digitally and precisely control the total delay in the oscillator core. This makes it possible to achieve a programmable delay, hence attaining potential progra...
متن کاملMicrophone Array Post-processor Using Instantaneous Direction of Arrival
In this paper we describe a novel algorithm for postprocessing a microphone array’s beamformer output to achieve better spatial filtering under noise and reverberation. For each audio frame and frequency bin the algorithm estimates the spatial probability for sound source presence and applies a spatio-temporal filter towards the look-up direction. It is implemented as a real-time post-processor...
