[backcolor=rgb(222, 240, 251)]The linear regulators or switching regulators we use generally have a maximum current limit. What does this mean specifically? Does it mean that if the current exceeds th...
50mA current drives LD, the output power of LD is 30uW. 50mA current drives LD through the bias Tee circuit, so the output power of LD should also be 30uW. Why does the power of LD increase 20 times a...
This is purely for experimental demonstration:I built a project, which contains two C files (fun.c and main.c). Both C files need to reference the array elements in the custom header file disp_tab.h. ...
Hello everyone! When I use modelsim-altera simulation, there are many warnings. The warning content is: Warning: CONV_INTEGER: There is an 'U'|'X'|'W'|'Z'|'-' in an arithmetic operand, and it has been...
