The circuit uses a 2N3904 NPN transistor and a 2N3906 PNP transistor, which operate as a high-gain amplifier. ... 0 comments on “ Simple two-transistor circuit lights LEDs ” Leave a Reply Cancel reply ...

Most of the circuits we have found on the internet have one thing in common, and that is they all have a two-transistor configuration. And for our first circuit, we tried something similar. Not only ...

We can improve the circuit and obtain the circuit from Figure 2.1a, e.g. we can make it more linear and less dependent from the change of the transistor T1. Figure 2.1b shows the improved circuit for ...
