The circuit takes advantage of the low current and voltage requirements of the VFDs — the whole thing runs from a USB boost converter — by wedging them between a 2N3904 input stage and a 2N200 ...

The other two pins are the Source and the Drain. This is a real gap created by silicon dioxide, the “Oxide” in MOSFET. If that sounds like glass, a really good insulator, I would say well yes ...

To enlist in the Army, aspiring recruits typically must take the Armed Services Vocational Aptitude Battery (ASVAB) test and earn a passing score. The ASVAB, with a maximum score of 99, requires a ...

How do we find the values of junction capacitances? Well, we re fortunate if manufacturers data is available. For instance, for the 2N3904 transistor, capacitance data is available for reverse bias ...
