I want to build a constant current source within 20mA. The diagram is as follows:I first built it according to the circuit diagram (1), but the effect was not ideal. When I changed RL, the current cha

F103+SRAM board, with serial port and IIC, 6.5mil trace, 8mil/16mil via, TOP/GND/PWR/BOTTOM stack. I took a screenshot for easy viewing. If you have time to help me take a look, please comment @ me an
This paper introduces the design theory of broadband 360-degree analog phase shifter. The linear phase modulation, balanced insertion loss fluctuation, broadband etc. of the phase shifter are discusse
