This section covers basic electronics tutorials in various electronics domains. If you are an absolute beginner, this section is the starting point to learn the basic electronics concepts. Once you are the done with understanding the basic concepts, head towards the electronics circuits section and try your hands on few circuits.
Designing an efficient Power Supply circuit is not less of a challenge. Those who have already worked with SMPS circuits would easily agree that the flyback transformer design plays a vital role in designing an efficient power supply circuit. Most times these transformers are not available off the shelf in the exact same parameter that suits our design. So in this…
Operational Amplifiers or Op-Amps are considered the workhorse of Analog Electronic Designs. Back from the Analog computers era, Op-Amps have been used for mathematical operations with analog voltages, hence the name operational amplifier. To date, Op-Amps are extensively used for voltage comparison, differentiation, integration, summation and many other things. Needless to…
Today, electronic devices have shrunken in size than ever before. This enables us to pack in tones of features in compact portable devices like smart watches, fitness trackers, and other wearable devices, it also helps us to deploy remote IoT devices for cattle monitoring, asset tracking etc. One common thing among all these portable devices is that they are battery operated…
Previously we learned about Clipper Circuits, which are used to clip off the positive or negative part of the Alternating waveform. Today we will learn about Clamper circuits which are used to clamp the DC level of the output signal without distorting the waveform i.e. they are Level Shifter circuits. It can be designed using capacitor, diode and resistor. The…
Relay logic control systems are truly a foundation of industrial automation, and electromagnetic relays are necessary to perform switching actions in these conversion systems. The relay logic circuits also utilise relays along with switches, motors, timers, actuators, and contactors to form ON/OFF control systems effectively. Though relay logic control proves to be effective…
A diode is one of the basic components that are commonly used in electronic circuit designs; it can be commonly found in rectifiers, clippers, clampers and many other commonly used circuits. It is a two-terminal semiconductor device that allows the current flow in only one direction, that is, from Anode to Cathode (+ to -) and blocks the current flow in the reverse direction…
LED bulbs are said to be 80% more efficient than other conventional lighting options like fluorescent and incandescent bulbs. The fast adaption of LED bulbs is already noticeable around us and the global LED bulb market value has reached to around $5.4 Billion in 2018. A challenge, in designing these LED bulbs is that LED light, as we know works on DC voltage and the mains…
Back in the ENIAC era, computers were more analog in nature and used very few digital ICs. Today an average Joe’s computer works with multiple voltage levels, people who had seen the SMPS of a CPU would have noticed that your computer requires ±12V, +5V and +3.3V to operate. These voltage levels are very important for a computer; a specific voltage determines the state of…
As the name suggests, Clipper circuit is used to “clip” a portion of input signal without distorting the remaining part of the waveform. It is a wave shaping circuit. This can be very useful in the circuits where the input signal attains a higher value of voltage than the expected one. These circuits can be implemented in various ways according to the configuration or…
An average household microwave oven operating at 110/220V AC can produce upto 2800V inside it, which is dangerously lethal. Besides that it also has a lower level AC voltage around 3.5V to light up the filament and a regulated DC voltage like 5V/3.3V for the digital electronics part like the display or timers to operate. Have you ever wondered…
Maxwell equations are the fundamentals of Electromagnetic theory, which constitutes a set of four equations relating the electric and magnetic fields. Instead of listing out the mathematical representation of Maxwell equations, we will focus on what is the actual significance of those equations in this article. The Maxwell’s First and Second equation deals with static…
To explain in simple words a Transimpedance amplifier is a converter circuit which converts the input current to a proportional output voltage. As we know when current flows through a resistor it creates a voltage drop across the resistor which will be proportional to the value of current and the value resistor itself. Here, assuming the value of resistor to be ideally…
