This design work can be used for a single lithium-ion battery operated portable electronic system. The input voltage range of the converter is 3.5V-5V and the maximum load current can be as high as 950mA. A high switching frequency of 1MHz is used for the design to achieve a smaller inductor and capacitor value as well as a lower voltage ripple. The functional blocks of this designed synchronous buck converter include power stage circuit, compensated error amplifier, PWM comparator, dead time generation circuit and gate driver. Based on TSMC 0.35 um process, the whole circuit system as well as each functional block are simulated and the simulation results show that the output voltage ripple of this synchronous buck converter is smaller than 10mV. At 6Ω load resis...

Hello Ahmed, I've got your name from Nikolaos, he told me that you're the best person to carry out my project. I'm working on ASIC project which is to be implemented in 65 nm CMOS technology. I have the golden model of the algorithm written in MATLAB and I need to transfer it into Verilog RTL. Nikolaos did some of the work but he got new job so he quit. Please tell me if you can help me in so. Best regards,

Hello, I need 3-channel PWM amplifier. What it does: It receives TTL logic PWM signal and amplifies it to 12-24V in order to drive power RGB LEDs. The TTL logic levels shall be both 3.3V and 5.0V; The power supply shall be in range 12-24V; The output PWM shall be in range 12-24V; Consider attached drawings. Notes: * In case of connection 3.3V MCUs you should consider that most of them are intolerant to 5.0V. Thus, in order to prevent 3.3V MCUs from being damaged it is okay to put jumper which switches between 3.3V and 5.0V levels. * Please try to make amplifier as cheap as possible preserving stability and quality; * Logic side connections shall be pins, 12V side connections shall be soldered thru-holes; * Single-sided PCBs preferred; On output I need: 1. All files t...

We have 4k video from a GoPro 3+ that is wavy. Unlike most video stabilization software, the camera is not moving, just some vibrating which combined with the rolling shutter is creating wavy distortion in the recording. We need special a special stabilization code written that combines the scene from multiple frames to correct the vibration distortion and cmos rolling shutter effect.

You must have experience with digital imaging algorithms, compression algorithms, CMOS sensors, and creating BSP's.

This messed up the responsiveness of the site so we we're forced to disabled it. Secondly, the site has a hotspot plug-in on two pages. We request a solution to make these hotspot stay in a fixed place on the map/image of interest because presently if you resize the browser or display it in anything other than a large display setting, the hotspots will appear all over the place instead of where we intend them to be.

Altium schematic and PCB tasks, mostly small. The first task would be to draw a schematic using a PIN photodoide Hamamatsu QFP5.8-6 TO along with a OPA340NA amplifier (the SOT-23-5 package) using the circuit in the enclosed drawing (), it will also need a power regulator (e.g. as per the ). And solder pins for Vin, GND, Vout. Once the schematic is completed then I need a PCB drawn up which will fit in the outline of the enclosed file (Rear ). After that I have various other projects (some similar, some larger). thanks Andrew

Design a two stage CMOS amp using a simulation tool (PSPICE). Deadline: May 10, 2014 at 9PM Los Angeles, USA time zone.

I am looking for someone to make the code list to run a multi channel home amplifier through rs232 via a Itach IP adapter. The app that will be running the device will be roomieremote, but will also be run by other software in the future such as Fibaro. The coding has to be writen very specifically to roomieremote's specs, but I also require a basic XML code list so that I can use it later with other software and devices. I have the rs232 control protocol for the amplifier as well as the specs roomie requires to use for its software. I do not know how to make a complete list based on the codes given by the amp manufacturer and that is why i am posting this project here. This should be very simple and extremely quick for anyone with coding experience. The code will als...

The aim of the job is to integrate a pitch shifting (2 semitones) within a custom made software written with C++. The software works with ASIO drivers and external hardware (amplifier: RME Fireface UCX, microphone and headphones). The system is Windows XP. The software directs the voice from microphone to headphones real-time, doing also recording. The saved files are then played back. All other functions are already defined by the existing code. A pitch shifting mode needs to be integrated as an additional function (both for online monitoring and recorded files). It has to work with a low-latency (no perceptible delay from processing is allowed). It may possibly use free libraries like this one, but it is up to the coder: The thing is a bit urgent
