Analog Electronics deals with electronic systems that has a continuous variable signal. In this section we will discuss about various analog electronic projects that can be used to design your own amplifiers, oscillators, filters, analog converters, waveform generators and other analog circuits as required by your application.
The Wireless Electricity Transfer concept is not new. It was first demonstrated by Nikola Tesla in the year 1890. Nikola Tesla introduced electrodynamics induction or resonant inductive coupling by lighting up three light bulbs from the distance of 60 feet from the power source. We have also built a Mini Tesla Coil to transfer the energy.

Most of electronics deals with Tracing Curves, be it the characteristic transfer curve for a feedback loop, a resistor’s straight VI line or a transistor’s collector voltage versus current curve.
These curves give us an intuitive understanding of how a device behaves in a circuit. An analytical approach might involve plugging in discrete…
Amplifiers are integral part of Electronics which are used to amplify low amplitude signals. Amplifier plays a very important role to boost the signal, specially in Audio and power electronics. We previously built many types of amplifiers including audio amplifiers, power amplifiers, operational amplifiers etc. Apart from them you can learn many other commonly used…
Op-amp or Operational Amplifier is the backbone of Analog Electronics and out of many applications, such as Summing Amplifier, differential amplifier, Instrumentation Amplifier, Op-Amp can also be used as integrator which is a very useful circuit in analog related application.
In simple Op-Amp applications, the output is proportional to…
At the outset, driving a motor might seem like an easy task – just hook the motor up to the appropriate voltage rail and it will start rotating. But this is not the perfect way to drive a motor, especially when there are other components involved in the circuit. Here, we will discuss one of the most commonly used and efficient ways to drive DC motors, the H-Bridge circuit.…
There are several critical machines or expensive equipment which suffer damage due to vibrations. In such a case, a vibration sensor is required to find out whether the machine or equipment is producing vibrations or not. Identifying the object which is continuously vibrating is not a tricky job if the proper sensor is used to detect the vibration. There are several types of…
In previous tutorial, we started with Understanding an Inductor and It's Working, now it is time to explore the different combinations of Inductors. In electronics, Inductors are the most commonly used components after the capacitors and resistors, which are used in different combinations for different applications. We have also used inductor to build metal detectors and…
Frequency to voltage converter converts the frequencies or pulses to the proportional electrical output such as voltage or current. It is an important tool for electromechanical measurements where repeated events are occurring. So, when we provide a frequency across a frequency to voltage converter circuit, it will provide a proportional DC output. Here we are using KA331 IC…
In simple terms, the oscillator is a circuit which converts DC power from the supply source to the AC power to the Load. Oscillator system is built using both active and passive components and it is used for the production of sinusoidal or any other repetitive waveforms at the output without any application of an external input signal. We discussed few oscillators in our…
Pulse Width Modulation (PWM) is a powerful technique where width of the pulse is changed by keeping the frequency constant. The technique is used in many control systems today. The application of PWM is not limited and it is used in wide range of applications such as motor speed control, measurement, power control and communication etc. In PWM technique, one can easily…
Diodes Incorporated extends its transistor family with release of NPN and PNP power bipolar transistors in a much smaller form factor of 3.3mm X 3.3mm. The transistors enable higher power density designs in gate-driving power MOSFET’s and IGBTs, Linear DC-DC step-down regulators, PNP LDOs and load switch circuits which helps in applications which require 100V and 3A…
One common feature that is used in almost every embedded application is the ADC module (Analog to Digital Converter). These Analog to digital Converters can read voltage from analog sensors like Temperature sensor, Tilt sensor, Current sensor, Flex sensor etc. In this tutorial we will learn What is ADC and How to use ADC in Atmega16. This tutorial includes…
