What is source and sink current? Source and sink currents are used by integrated circuits such as microcontrollers, digital signal controllers, digital signal processor and any application specific integrated circuits. Sometimes these are being interchanged by others that it should not be. In this article we will know the answer of the question what is source and sink current. Source

Designing control systems needs a tool to speed up the task. Here are the tools that can be used in control system design. Matlab control systems toolbox is in the top of the list then followed by Simulink control design. I also included here simpowersystems because of its usefulness in power electronics. Control system is not as easy as ohms

Below is the step by step procedure on how to setup bode plot in Simulink. Bode plot is a graph of gain and phase of a system. In a bode plot you can get the gain and phase margins and know if the system is stable or not. To demonstrate this properly, consider the Simulink model in Figure 1. You should

LTspice is a very good circuit simulation tool for electronic circuits. Thanks for Linear Technology for sharing such a nice tool. In this article I will teach Monte Carlo Simulation using LTspice with Step by Step Tutorials. Monte carlo is an analysis method used by design engineer to increase the robustness and reliability of their products. It is all about
READI remember when I started to study matlab I was searching for matlab control design step by step tutorials but I have not seen any. Self studying is not easy, it took me sometimes to learn and get what I want. However, we will not having the same experience. I am about to share to you matlab control design step

Charging and Discharging Capacitive Circuits The voltage on a circuit having capacitors will not immediately go to its settling state unlike purely resistive circuits. When a potential difference is applied to an RC circuit the like of Figure 31 below and then S1 is closed, the voltage across the capacitor will exponentially rises from zero to its final value. At
READFuse is a very simple electrical part and yet needs to be properly selected. Its role in the circuit is very important actually. Selecting a right fuse starts with a good understanding on fuse electrical parameters. There are some important fuse electrical parameters to consider. These are the Current Rating, Ampere Square Seconds, Breaking Capacity and Voltage Rating. Fuse Electrical Parameters Explanation 1.

There are several circuit analysis methods. In this article I will discuss the most common. In the proceeding discussion I will just use a resistor as an example but in actual application it is not limited to it. Popular Circuit Analysis Methods 1. Ohm’s Law Ohm’s law is very popular in resistive circuit. It states that the current flowing through

In this article I will discuss Fuse Operation and Principle. A fuse is a simple electrical part which consists of a wire and terminals on each end. It is plainly a passive device which protects the circuit in the event of a large current. When this happens, the fuse element will open and the circuit will become discontinuous. Fuse operation

Current transfer ratio is comparable to BJT’s HFE or beta (β). This is the ratio of the optocoupler’s collector current to the forward current. Current transfer ratio is popular by its abbreviation CTR. CTR is simply the measure of the optocoupler’s transfer efficiency. If we recall the basics, optocoupler is a semiconductor device with a light source and a detector.
