july/august 1984 a power-photo transistor The 2N3055, strange though it may seem, can operate very well as.a photo transistor, as the circuit here shows. The power transistor must be made light ...

Here is a project that involves the electric side of your bike or car! we are building a 12V Bulb flashing circuit fully documented. You will not need advanced electronics skills, the minimum ...

Safe 12V car adapter described here can be used to limit a +12 volt car battery current, available from the in-dash cigar lighter power port, to below 2.6 Amperes for use with portable electronic ...

Abstract: This study presents a high-linearity K - band single-pole double-throw (SPDT) switch with asymmetric topology in a 65-nm CMOS process for 5G applications. To simultaneously obtain high power ...
