In this post I have explained some important current mirror circuits, and how to design practical circuits using current mirror concepts. Current Mirror Definition A current mirror is a circuit that copies a current through one active device by regulating the current in another active device in the circuit, maintaining a constant output current independent […]
Electronics Theory
Inductor Working and Designing, with Formulas
In this post I have explained all the basics of inductors, its working principle, and how to design inductors with the help of formulas and calculations. Inductors are vastly used from mobile, laptop chargers to high-end communication equipment like mobile base stations to the satellites orbiting the earth. Let us take a deep dive into […]
Difference Between Op amp and Comparator
In this article I have explained the main differences between op amp and comparator, and try to understand why op amps are not ideally suited to be used like compartaors. We also learn the main advantages of using compartaor ICs in comparator applications. Basically, you will find many electronic lectures or publications talking about using […]
6 Simple AC Bridge Circuits Explained
An AC bridge is a circuit which can be used for measuring parameters like capacitance, resistance, Inductance using differential method, by comparing them with known values of similar components, positioned diagonally across a bridge circuit, and through an analogue meter placed at the center of the bridge. Before we begin talking about the AC bridge […]
High Stability of Crystals in Oscillator Circuits
The stability of good quality RC oscillators can be expected to be around 0.1%, while normally we can assume the stability of LC oscillators to be up to 0.01%. When a much higher level of stability is required, we have to use a crystal based oscillator circuit. The main reason why crystals are so important […]
Boolean Algebra in Logic Circuits Made Easy
Boolean algebra is a assortment of basic mathematical techniques applied to signify and communicate the logical procedures that happen within a digital circuit. Difference Between Boolean Algebra and Common Algebra Boolean algebra is much like common algebra. The main distinction is that in contrast to common algebra, in which we have parameters that can be […]
