Over the recent weeks here at Hackaday, we’ve been taking a look at the humble transistor. In a series whose impetus came from a friend musing upon his students arriving with highly developed ...

Transistors are inevitable parts of Electronic circuits. The success of a circuit design lies in the selection of proper transistor type and calculation of voltage and current flowing through it. A ...

In Parts 1, 2, and 3 we took a closer look at calculating “ac” gain and how to desensitize the circuit to temperature and transistor parameter variations. In part 4 we consider the effects of a ...

A breadboard is a great prototyping tool for verifying the sanity of a circuit design before taking the painstaking effort of soldering it all together permanently. After all, a mistake in this stage ...

This file type includes high resolution graphics and schematics. The spread of h FE values in a batch of transistors may be wide enough to cause unreliable performance during mass production of a ...
