Choosing the Right Diode – Types and Uses Explained for Beginners
https://www.electronics-lab.com/choosing-the-right-diode-types-and-uses-explained-for-beginners/
From small LED drivers to rectifiers to Switch Mode Power Supplies (SMPS), the diode is a key component in each of those everyday appliances. They are also used in charging LED indicators and reverse polarity protection circuits in router chargers and many more; diodes are used everywhere, but this little device often does not get […]
Diode Clipping Circuits
https://www.electronics-lab.com/article/diode-clipping-circuits/
Diode Clipping Circuits The diode clipper is an electronic circuit consisting of a diode(s) that clips or cuts off an input signal. The output of the clipping circuit depends on the diode orientation and input signal. Such a circuit is termed, Diode Clipper. The clipped-off signal produced at the output becomes flat when a certain […]
Zener Diodes In Theory and Practice
https://www.electronics-lab.com/zener-diodes-theory-practice/
David Jones made a tutorial on the fundamentals of zener diodes over his EEVblog youtube channel. David started the tutorial comparing between zener and regular diode. Both have the same characteristics and same I-V chart, but zener is designed to work in the negative voltage region.”In theory” the regular diode can work in the negative […]

Tiny low current 9 VDC Regulated Power supply designed around bipolar transistor and zener diode. The circuit is known as series voltage regulator or emitter follower voltage regulator. The unregulated supply fed to input and the circuit regulate the voltage and provide constant 9V DC, 250mA. The zener diode provides the reference voltage to the […]
Build an op amp with three discrete transistors
https://www.electronics-lab.com/build-an-op-amp-with-three-discrete-transistors/
by Lyle Russell Williams: You can use three discrete transistors to build an operational amplifier with an open-loop gain greater than 1 million (Figure 1). You bias the output at approximately one-half the supply voltage using the combined voltage drops across zener diode D1, the emitter-base voltage of input transistor Q1, and the 1V drop across […]
