Cmos amplifier design jobs
Hi sagradoamicus, I noticed your profile and would like to offer you my project. We can discuss any details over chat. We are trying to design an optical remote flash slave. Basically what this device will allow us to do is trigger off camera flashes places in different locations. The main camera flash is connected with electrical cable to the camera. The off camera flashes will be connected to the optical remote slave (the circuit we are designing) located anywhere from 3 to 30meter away. The way the trigger will work is that it should detect the flash pulse from the main camera flash and triggers the flash that it is connected. Our device will have a micro controller which will control the on/off, sleep power saving mode and charging mode. Here is how the light pulse from a flash...

...Project Description: The goal is the design of a 4-bit adder. Inputs are two 4-bit numbers A & B. Output is 4- bit sum and a carry. 5. Step-by-Step Description: First Step: - Start with the design of a minimum sized inverter, i.e., Lp = Ln = Lmin = 250 nm, and Wp = Wn = Wmin = 350 nm. Simulate the circuit schematic. From the voltage transfer characteristic, identify the switching voltage VM and the noise margins. - Gradually increase the width of the PMOS transistor as multiple of Wn, i.e., use Wp = 2Wn, Wp = 3 Wn, …. etc until you reach a matched inverter. Verify that the inverter is indeed matched by showing that VM ≈ VDD/2. - The size of the PMOS transistor in the matched inverter will be used to specify the size of all transistors in the ...
...energy conversion in CMOS circuits which is necessary to represent the change of signal value. There is one irreversible energy conversion where electrical energy can be converted into heat. To change this one way conversion, there has been introduction of another form of energy called “ Magnetic field energy”. This is often referred as Energy –recovery model. This is not possible for the circuits running with Dc power. So, it is very necessary to study the circuits running with AC power which acts as a clock. There is another method called “Adiabatic Switching”. This is used to reduce the energy dissipation. Clocked CMOS circuits having gradual rising and falling power clock are expected to save more energy. Top...

We have a cmos camera (Terasic TRDB-D5M) and FPGA development kit (DE2-115). In fact, we have a demo project. But in this project, the image is transferred to the monitor via the VGA port. Also, the image resolution is 640x480 or 800x600 and frame rate is about 30 fps in this demo project. Camera supports 5 MP and up to 70 fps. The expected from the project are as follows: -- we want to use the existing features of the camera (5 MP or 70 fps). -- we want to send the images to a computer over ethernet port. Please contact me for questions.

Design a single-transistor amplifier that delivers at least ten times as much power to the load as it draws from the source. In other words, the power gain must be at least 10 (10dB). The signal source has a resistance of 1kΩ and the load has a resistance of 10kΩ. Your power supply is 5V. You are allowed to use a BJT or a MOSFET, as well as any amplifier configuration of your choosing. A SPICE template file has already been created for you and is available for download from Blackboard. It contains all the information you need besides the actual circuit.

We are looking for a capable electronics engineer who can design a CMOS Board Camera based on an Aptina AR0134, MT9M021/31 or similar sensor (1.3MPixel). The camera will operate in snapshot mode, taking an image on demand from an external trigger. (max 2 images per second) It should have a good quality board bayer interpolation, either using a dedicated Image Signal Processor OR an FPGA. It should output data via a Digital Data Bus as RGB or YUV (RGB preferred) The camera will be controlled via SPI, I2C or similar. Advanced camera features such as Auto Exposure, Auto White Balance, Auto Focus etc will not be required. For development and testing a board mount lens will be used. At a later stage the board will eventually be fitted behind a zoom lens module, b...
