Frequency Compensation of Op-amp and why it is important in your Op-Amp Circuits 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… |

Variable Output Voltage DC to DC Boost Converter using MC34063 In the previous tutorials, we demonstrated detailed design of 3.7V to 5V Boost Converter using MC34063 and 12V to 5V Buck Converter using MC34063. Today we will use the same MC34063 IC to build a DC to DC Boost Converter circuit which can convert small voltage like 3v to higher voltage upto 40v. So here MC34063 IC is used a Adjustable DC-DC Converter. … |

Driverless LED Lights The Great American Businessman and Inventor of light bulb – Thomas Alva Edison once said that “We will make electricity so cheap that only the rich will burn candles”, which certainly has become the case today. From small house to paved roads to big industries, we can notice AC lights illuminating our environment after the sun goes down. Earlier lighting systems employed… |

12V 1A SMPS Power Supply Circuit Design on PCB Every Electronic device or product requires a reliable power supply unit (PSU) to operate it. Almost all devices in our home, like TV, Printer, Music Player etc. consists of a power supply unit built into it which converts the AC mains voltage to a suitable level of DC voltage for them to operate. The most commonly used of type of power supply circuit is the SMPS (Switching… |

Schottky Diode – Characteristics, Parameters and Applications 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… |

Simple H-Bridge Motor Driver Circuit using MOSFET 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.… |

An Overview of Dual Converters In the previous tutorial, we saw how a Dual Power Supply Circuit is designed. Now, we learn about Dual Converters, which can convert AC to DC and DC to AC at the same time. As the name suggests, Dual Converter has two converters, one converter works as a rectifier (Converts AC to DC) and the other converter works as an inverter (converts DC into AC). Both converters are… |

What is JFET: Its Construction, Working and Biasing Techniques JFET is a Junction gate field-effect transistor. A normal transistor is a current-controlled device which needs current for biasing, whereas a JFET is a voltage-controlled device. Similar to MOSFETs, as we have seen in our previous tutorial, JFET has three terminals: Gate, Drain, and Source. JFET is an essential component for precision-level voltage… |

Lead Acid Battery: Working, Construction and Charging/Discharging Almost every portable and handheld device consists of a battery. The battery is a storage device where energy is stored to provide power whenever needed. There are different types of batteries available in this modern electronics world, among them Lead Acid battery is commonly used for high power supply. Usually Lead Acid batteries are bigger in size with hard and heavy… |

Short-Circuit Protection Circuit Short circuit protection is an unintended connection between two terminals which are supplying power to the load. It can happen both in an AC and a DC circuit. If it is an AC supply, then a short circuit can trip the power supply of the whole area, but there are fuses and overload protection circuits at many levels, from the power station to the house. And if it is a DC… |

Asynchronous Counter An asynchronous counter (or ripple counter) is a sequential digital circuit in which the outputs of flip-flops are connected in series, so that the output of one flip-flop serves as the clock input to the next stage. Not all flip-flops may change state at the same time as synchronous counters, so asynchronous counters are easier to design but may experience propagation delays. Table of… |

Voltage Controlled Oscillator (VCO) Most of the consumer electronic devices around us, such as mobile phones, TVs, Radios, and MP3 players, are a combination of Digital and Analogue electronics. Wherever wireless transmission/reception, or audio signals are involved in an electronic design, we will need periodic oscillating electronic signals. These signals are called Oscillating signals and are very useful in… |
