Cmos amplifier design jobs

audio amplifier

I am making this request because my project is a portable amplifier to pass the year but to pass the year I have to have the project done.

This project is to design (including the schematics and PCB layout) of a high voltage RF amplifier. The Vp-p should be 600V and in the frequency range of 10KHz-5Mhz. More information will be provided. The current posting is only for schematics.

You are to design an integrated circuit CMOS operational amplifier that has a differential input and single-ended output, and that meets the described specifications in the attached file

The project will require playback and looping of 10 MP3 audio files of aprox 100MB each, the ability to switch between files, and a timer function to turn the machine off. The software should run on a low cost microchip to be embedded into our project. We will also need a low cost audio amplifier, speaker, headphone output, buttons for on/off, volume, timer, and sound selection

I have a code for wideband spectrum sensing due to LNA, but the code models the LNA with memory. I need to do the simulation for LNA without memory case.

This project is to refine existing firmware for a battery operated embedded device. This project is primarily to quickly and efficiently debug and optimize the code. The device is based on the ARM architecture and we use Free RTOS as our operating system. The device has a cmos camera, IR camera along with bluetooth, wifi and zwave wireless radios. The device also has voip capability so some experience with that would be a plus. The device connects to both PC's and smart phones. Our hardware includes the ST Micro ST32 and we use the TI BLT/WIFI chipset. This project has milestones but many new ones will be created as the project progresses into achieving customer requirements.

we are using the proposed techniques to reduce leakage power such as MTCMOS ( Multi threshold CMOS technique), Power Gating, Dual Stack, GALEOR and LECTOR. RCA and CLA circuita designed by using the above mentioned techniques, power dissipation is calculated for each technique and is compared with general CMOS logic of RCA and CLA. Simulation results show the validity of the proposed techniques is effective to save power dissipation and to increase the speed of operation of the circuits to a large extent. We need simulations. Tools used for simulation must be Modelsim, Hspice, LT spice, Xilinx

A Bi-polar Junction Transistor (BJT) needs to be designed in a software called Advance Design System (ADS) Software. Project Description: Design a low noise amplifier using an Infineon RF transistor BFP640. The amplifier is to be used to amplify the L2 GPS signal and so the centre frequency is 1227MHz and bandwidth 40MHz. The requirements over the entire bandwidth are: a noise figure of less than 1.0dB, a gain of 20dB ±0.3dB and S22 should be less than -15dB. The circuit will be used in a portable device. Everything is in the zip file. Approach and requirement of the project is in the file "H63TCE Coursework ". This is the main file for the work. You can access the data sheets and other material required for the coursework aswell. ...

To design an operational amplifier by using Spice or spectra

Hi, have 2 school homework questions unsure of. Will like to find out the exact steps as to how to solve them.

I need a small and easy to build soft start module circuit generated along with a basic wiring diagram to build it with protoboards. Once we are happy with the performance, we plan to incorporate other electronic systems onto a single board and build a custom interface. For now, the project is simply for the design/ prototype build instructions.

I need a schematic to take a raw Omron photo electric (EE-SX1042) sensor and condition the circuitry unit to accept 5 - 24 volt DC power with an output to trigger an Arduino input in the 1 - 20 Hz switching speed range., The unit also needs an LED indicator light to indicate on - off status of the sensor. This circuit will mimick the Omron EE-SX772 built in amplifier unit.

...microphone has 0% of volume (-24dB or lower maybe), on each frame the balloon loses 2,2 inflation points… so you fight against that -when the ballon gets to 100, it flies away, and you get a new one. -when the time goes down to zero, there will be a finish screen saying how many points and stars you got. The perfect score should be 10 balloons in 30 seconds (that’s if you put a loud guitar amplifier against your telephone, for example). So 5 or more ballons give you 3 stars, 3-4 ballons=2 stars. 1-2 ballons: 1 star. 0 ballons, 0 stars...

...preamplifier will have a microphone input, and its output will drive a power amplifier. A schematic is shown in Figure 1. The DC supply voltages are provided by a battery pack or by an electronic power supply. The first stage is a common emitter PNP with voltage divider bias, and the second stage is a common-emitter NPN with voltage divider bias. It has been decided that the amplifier should operate from 30 V DC to get a large enough signal voltage swing to provide a maximum of 6 W to the speaker The potentiometer at the output provides gain adjustment for volume control. The input to the first stage is from the microphone, and the output of the second stage will drive a power amplifier The power amplifier will drive the speaker. The preamp is to oper...

...audio amplifier, but the chinese case production company want the drawings made by SolidWorks. They want to get a file. And that would be your mission: - solid works drawings of the audio amplifier. In Detail: - Frontpanel, Rearpanel, Top&Bottom Plates, Side Panels simplified without the Heatsink profile. Together with the Mounting Square Profiles, the Sandblasted Power Push-Button, the two Alu knobs and the zylindrical feets. - And if possible together with the Printed fonts. Your work does not include the plastic parts. If you miss a measure of length in my drawings you can estimate it. That's OK, because I will correct them with my 3 months trial SolidWorks Software. The SolidWorks amplifier Design is not for presentation. It is just for th...
