Design a ASIC chip of MEMS accelerometer，using cadence virtuoso and CoventorMP
Hi, I am looking for some help in designing a custom sound card. This card will interface with multiple MEMS digital microphone process them and make it available for connecting to a computer. Think about it as something like Amazon Alexa echo which has multiple microphones. An open source hardware design is available here: https://respeaker.io/usb_6+1_mic_array/ In my case, the mic will be away from the boards, and number of mics will be significantly more (50+). So teh audio CODEC and central DSP chip (XMOS in this case) will have to be way more powerful. I need a complete design for this board. Can you please give me an estimate of how much this might cost and how much time it will take?

I need a micro-sized self contained LED solution that does not require wires or batteries that require replacing. I was thinking of something that could operate from ambient RF, Neodymium Magnets, or some other innovative method that can make the LED stay lit. The space that this device needs to fit in is 5mm x 5mm x 7mm. Since I'm not an engineer I am relying upon your expertise and knowledge to come up with a solution. I can say I've researched it a bit and found some interesting concepts but the simple truth is that I need it to be able to be on all the time and never require batteries to be replaced or some other maintenance. They cannot require removal to charge - they must be able to turn on and stay on (essentially forever... or at least for 4-5 years). The image p...

Our primary objective is to obtain I2S data from 2 sensors(I2S Mems Microphones) onto ESP32 and transmit the data wirelessly to an Android Device. Data will be acquired from each sensor at 96ksps with 24bit resolution. Most importantly there should be loss less data transfer to the android device and should be saved to a file. This is an application to LIVE-STREAM data to the android device from ESP32 device. Although, microphones are used, this is NOT an audio playing application, rather it is a data-acquisition application. Thus, raw data( without any compression or loss) needs to be recorded and saved. Detailed features that are required :- 1. Total data rate = 24bit x 96ksps x 2ch =4.6Mbps. 2. The communication needs to be done between the esp32 device which will have ...
I am looking for a freeelancer who can design MEMS sensor fusion . The sensors include accelrometer magnetometer and gyro. Freelancer should be able to implement necessary firmware to identify motion of the object in multi axis. freelancer should have experience in this particular want to use it for indoor tracking of object.
An experimental MEMS device will operate at a high frequency, and the resistance of the device must be kept at 50 Ohms, even under activity. As shown in the schematic file (see attachment ), the MEMS device consists two IDTs (transducers). Each IDT has effectively R < 0.1 Ohms. The IDT image is in deviceBreakdown.jpg. Requirement: Design the auxiliary circuit so that Req is 50 Ohms, plus or minus 5 Ohms. Inputs: The inputs to IDT1 and IDT2 must have a sine signal with a frequency of 30-35 MHz and VPeak of 27 V (V max). Vpp (V peak to peak) is 56 V. Alternatively, it may have a higher voltage may be 33 VPeak and 66 Vpp. The total power dissipated is 1-1.6 W. Complications: Due to high frequency, there is also potentially inductance L and capacitance C while the d...

I need an editor for my videos, I'm new to the editing so it takes so much time and I can't make it up as I am at this moment, I need editor that can edit gaming videos put up some mems here and there and can do better job than me, of course per vid I will give 20$ and if the channel getting better I will raise it as much as I can! The editor need to be at least 18+ have sense to memes and know how to not to get copyright when it's about putting some sound and affects, I'm playing call of duty warzone as it my main game right now! I will be happy to take someone in for making a good channel for youtube!

My laboratory is researching drug delivery with nanocapsules in blood plasma. We need a method to reliably separate the blood plasma and nanocapsules. The capsules have a mean diameter of 292 nm, and a higher density relative to blood plasma. We have turned to acoustofluidic MEMS devices, given prior reported results. We are looking to replicate the MEMS device reported in another paper. The Wu 2017 paper details the steps required to fabricate the device in Section 4. We are looking for someone who could: -Find a MEMS manufacturer to make the device. -Send us a quote. -Have it delivered to a university lab in Germany. Let me know if you have any questions.

The microphone in which the audio is being measured communicates with an I2S Philips audio protocol. A fast Fourier transform need to be implemented on an audio analysis coming from an ICS43434 or INMP441 microphone, the audio input comes from the MEMS digital microphone with I2S digital audio protocol. Using a STM32L496RG or a ESP32, direct memory access has to be implemented (DMA) so we have faster processing time to do the FFT, and transmit the data measured wireless, every second. Current code is working on STM32L4 and it is being able to get the dBA value out of the RMS calculation, but doesn't have the FFT implemented and also an exponential logharitimical moving average is needed to be implemented to calculate SLOW measurements (each second), the FAST measurement (125m...

The key elements of the design are a simple PCB with 6 surface mount MEMS microphones, one small loudspeaker, and electronics to perform A/D conversion on the 6 microphone streams and connect them to a USB 2.0 port, plus to take an output audio stream from USB, convert to analog and drive a small speaker (4-7cm diameter). This is really just an audio codec to USB bridge, with a USB to speaker driver. No other signal processing is required on the board. Power is supplied by the USB connection. The design much include the microphones, LEDs, board connectors, USB/codec IC and all necessary passive components. The designer should be familiar both with methods for ...

I would like to develop an application for iPhone where I can read the raw acceleration data from the iPhone MEMS accelerometer (x,y,z and Rx,Ry,Rz) (similar to vibsensor® and seismometer® applications). The program will cluster the acceleration for each certain period (for example the user will specify 1sec period so the program will record the acceleration for each 1 sec). Each signal (each 1 Sec signal in this example) will be used as an input to an equation ( I am going to provide the developer with this equation ). The equation output will be used to plot a 2D graph.
