Designing OR Gate using Transistor As many of us know an Integrated Circuit or IC is a combination of many small circuits in a small package which together performs a task. Like an Operational Amplifier or 555 Timer IC is built by a combination of many Transistors, Flip-Flops, Logic Gates and other combinational digital circuits. Similarly a Flip-Flop can be built by using a combination of Logic Gates and the… |

What is Bleeder Resistor and where it is used? Bleeder resistors are standard high value resistors which are used to discharge the capacitor in filter circuit. The discharging of the capacitors is really important because even if the power supply is OFF, a charged capacitor can give a shock to anybody. So it is really essential to add a bleeder resistor to avoid any mishaps. It also have other applications but the main… |

What is DCR in Inductors and how does it affect your circuit design Inductors are widely used passive components in electronics after resistors and capacitors. An ideal inductor stores energy in a magnetic field and delivers a smooth output current to the load. But in a practical circuit, an inductor also contains some low value resistance associated with its inductance property. During the flow of DC supply or to be specific in 0 Hertz… |

Understanding ESR and ESL in Capacitors The most used electronics components in any electronic design are Resistors (R), Capacitors (C), and the Inductors (L). Most of us are familiar with the basics of these three passive components and how to use them. Theoretically (under ideal conditions) a capacitor can be considered as a pure capacitor with only capacitive properties, but in practice a capacitor will… |

Current Regulators: Construction, Working and Design Types Just like situations in which we need to regulate the voltage in our designs, there are scenarios where we need to regulate the current that’s being supplied to a particular part of our circuit. Unlike transforming (changing from one voltage level to another), which is usually one of the major reasons for voltage regulation, current regulation is usually about keeping the… |

Current Mirror Circuit: Wilson and Widlar Current Mirroring Techniques In the previous article, we discussed about Current Mirror Circuit and how it can be built using a Transistor and a MOSFET. Even though a basic current mirror circuit can be constructed using two simple active components, BJTs and MOSFETs or using an amplifier circuit, the output is not perfect, as well as it has certain limitations and dependencies on the external factors.… |

RC Phase Shift Oscillator using Op-Amp When an RC phase shift oscillator employs an op-amp in its circuit, it becomes an electronic oscillator with a stable sine wave output. It functions by developing two groups of 180-degree phase shifts, one via the RC network and the other via an op-amp in an inverting circuit. Due to this phase shift arrangement, it produces nearly pure sinusoidal signals with extreme frequency stability and… |

Simple Curve Tracer Circuit: Tracing the Curve for Resistor, Diode and Transistor 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… |

What is Capacitor Leakage Current and How to Reduce It The capacitor is the most common component in electronics and is used in almost every electronics application. There are many types of capacitors available in the market for serving different purposes in any electronic circuit. They are available in many different values from 1 pico-Farad to 1 Farad capacitors and Supercapacitors. Capacitors also have different types of… |

Automatic Medicine Reminder Using Arduino When it comes to our loved ones, we always want to keep them healthy and fit. But what will happen if they get ill and forget to take medicine on time? We would be worried, right? At hospitals, there are many patients, and it is difficult to remind every patient to take medicine on time. The traditional ways require human efforts to remind them to take medicines on… |
