I drew this circuit before, but it is no longer used. I posted the PCB diagram. If anyone wants the schematic diagram and the light board diagram, please leave me a message and I will upload it as soo...
Diode as a temperature compensation circuit for transistors
Both diodes and transistors are made of silicon. As the temperature T increases, the transistor Vbe decreases, ib=VCC-Vbe/R7+R5 ib increases...
Today I used the built-in phase-locked loop of FPGA to divide the frequency by 10M to provide the clock for ADS805 to do AD sampling, the waveform is 500khz, in order to reduce the clock overshoot and...
