I would like to ask you, how can I use a transistor, a diode, and a resistor to build a constant current circuit? (What is the constant current? The question did not mention it.) Because the examiner ...
I have been making instruments recently. I have made several DS1302s with existing chips. They all worked properly. Then I didn't have enough new DS1302s, so I bought a domestic DS1302 from a gold med...
I watched Razavi's video and he said that the purpose of heavy doping is to make good contact with silicon and avoid diode and rectifying junction. Is this diode BS BD? And what is the reason for good...
