This is the first part of a series of posts that show an analysis of practical circuits that use an operational amplifier (op-amp).
This post’s subject is the LCD Keypad module, which allows to control a LCD display with buttons without wires and a protoboard.
The operational amplifier, or op-amp, has great utility on electronics. In this post, it’s shown the operation of this integrated circuit (IC).
Was invented a new method for production of a semiconductor nanomesh, which will be used in new electronic components.
Why does the electrolytic capacitor has polarity? Why there is a voltage limit? These and other questions are answered in this post.
Was developed the e-skin, an electronic skin light and flexible for robots, to obtain more information about the environment.
The MOSFET is another type of field effect transistor. Much more used than JFET and it’s the most important component for digital computers.
The junction field effect transistor (FET) is a component with many applications. In this post, are shown the structure and the operation.
The common base is little known configuration for amplifiers using BJT. This type is used in high frequencies.
In this post, it is shown another type of amplifier configuration using BJT. This time, it is the common collector or emitter follower.
