...project to the some point, I successfully set up the blocks and I got a certain results. Yet, it's needed to develop a transfer functions for each of the used blocks (XOR circuit, Filter, VCO - voltage control oscillator) in order to achieve the best results. Anyway, the structure I developed is not the best one, maybe there are some elements that are

We will supply files for 4 PCB boards in Altium Designer (Creative Commons) + company logo, and we would need that you add the logo in the boards, then supply the modified Altium Designer files + ODB++ manufacturing files + Gerber manufacturing files
...the idea of using a constant gm bias circuit to bias the amplifier. Design the bias network and determine the dimensions of all transistors. Due to area constraints, you can only use a resistor up to 40K Ohms and a maximum L of 10um. Also, do not forget that K > 20 is forbidden and your circuit needs a startup circuit! (Hint: Consider using m=4 to simplify

I want to build a product wi...el-reader The job is to design a schematic for a product which would meet the following requirements: Read animal RFID Ear tags(134.2Khz) at a range of 1 meter or more.(This is the difficult part) It will be made of two parts.1 - RFID Reader, 2 - Antenna Enclosure design is not required at this stage. Schematic only.
I am interested in having a simple breakout PCB board designed. The attached picture shows the preferable dimensions. The overall dimensions are firm, but the hole spacing can be adjusted to meet standards if necessary. Successfull delivery of schematic, PCB, and gerber files will result in prompt payment. Thanks!

Project Topic and Scope select a consumer product that has at least 10 parts, obtain all relevant information regarding its manufacturing, assembly and recycling phases, and, based on your findings, propose possible options through which the product design can be improved. Improvements include manufacturing, assembly and recycling practices that require fewer resources, have reduced handling time,...
I am looking for a ready made auction site, script. AM NOT LOOKING TO BUILD IT FROM SCRATCH Site must be auction type, REVERSE AUCTION
I have a script I am using with the nodemcu and everything works great. But when I upload that code to the wemos d1 and plug the ...compiles file and uploads fine and the serial monitor shows everything working correctly so I assume I have my pins running to the wrong pins :) could use some help getting a schematic on the two pins this thing needs lol
Hello, I have made the circuit attached. It is basically, a wattmeter with WiFi (ESP8266). It has been designed to be connected to an European plug (230VAC). -This wattmeter can turn on/off the current flow. -The ESP8266 will be programmed using a USB to TTL adapter. -It has 2 ways of measure the current (using integrated ADC in ESP8266, or using
Hello my name is Hugo and I need a PCB design and printing (it's about a gamepad or game controller [...]). I need a PCB to embed it in a retro-arcade console that I want to make. The PCB would be of the following dimensions: 91.1 x 54.9 mm. I do not care how you want to do it, eye, with little margin of size since they must fit in some pieces printed
