Introduction to Electronic Amplifiers
https://www.electronics-lab.com/article/introduction-to-electronic-amplifiers/
An amplifier is an electronic block that magnifies either potential signals (voltage amplifier), intensity signals (current amplifier) or both (power amplifier). The amplifier consists of two inputs which are the signal to amplify (see Input Signal on figure 1) and the supply of energy (see Power Supply). The output (see Output Signal) is the input […]

Colpitts Crystal Oscillator
https://www.electronics-lab.com/project/colpitts-crystal-oscillator/
This project is a Colpitts Crystal Oscillator Description Firstly, I suggest you to read the article in ARRL Handbook 2015, Chapter 9 – Oscillator Circuits and construction. Then saw a video showing the construction of the Colpitts Crystal Oscillator (with Buffer stage) here. Thus, I assembled the circuit as “ugly construction” using the same […]
USB to Serial converter using FTDI FT230X
https://www.electronics-lab.com/project/usb-to-serial-converter-using-ftdi-ft230x/
This USB to serial converter project is easy to build, it is simple and inexpensive. It is based on theFT230XS from FTDI Chip. Description The FT230XS is outfitted in SSOP-16 packaging. The first incarnation of FT230X chips got a nasty bug when the chip inadvertently goes into suspend mode triggered by certain byte sequences. The […]
