Comparison between silicon and germanium
Fulfilling requests, this post is a comparison between silicon and germanium, as base materials for semiconductors.
Optocoupler with phototransistor
The optocoupler electrically insulates a circuit’s input and output. The operation and some projects are shown in this post.
Darlington and Sziklai pairs
The Darlington and Sziklai pairs are settings with BJT transistors. The comparison between both and some circuits are shown in this post.
Meet the LM3915
The LM3915 is an integrated circuit that uses many operational amplifiers to measure voltage level or audio volume.
Circuit analysis with op-amp (Part 1)
This is the first part of a series of posts that show an analysis of practical circuits that use an operational amplifier (op-amp).
Operational amplifier: how does it work?
The operational amplifier, or op-amp, has great utility on electronics. In this post, it’s shown the operation of this integrated circuit (IC).
MOSFET: how does it work?
The MOSFET is another type of field effect transistor. Much more used than JFET and it’s the most important component for digital computers.
Junction field effect transistor
The junction field effect transistor (FET) is a component with many applications. In this post, are shown the structure and the operation.
