In a voltage-controlled current source circuit, as the name implies, a small amount of voltage across the input will proportionally control the current flow across the output loads. This type of circuit is commonly used in electronics to drive current-controlled devices like BJT, SCR, etc. We know that in a BJT the current flowing through the base of […]

Current Source and Current sink are two major terms used in electronics design, these two terms dictate how much current can leave or enter a terminal. For example, the sink and source current of a typical 8051 Microcontroller digital output pin is 1.6mA and 60uA respectively. Meaning the pin can deliver (source) up to 60uA when made High and

When designing an electronic circuit, there are lots of situations when a circuit requires different values of voltage and current sources. For example, when setting the preset voltage for an Op-Amp, it is very common to use a potential divider circuit to obtain the required voltage values. But what if we need a specific value of current?

Oftentimes in an electronic circuit, it’s absolutely necessary to use a special protection unit to protect the circuit from overvoltage, overcurrent, transient voltage, and reverse polarity and so on. So, to protect the circuit from these surges, Richtek Semiconductor introduced the RT1720A IC which is an oversimplified protection IC designed to meet the needs. The
A rectifier is a circuit that converts alternating current (AC) to Direct current (DC). An alternating current always changes its direction over time, but the direct current flows continuously in one direction. In a typical rectifier circuit, we use diodes to rectify AC to DC. But this rectification method can only be used if the input voltage

In our previous tutorial, we used a basic LED blinking program as a getting started with N76E003 guide, we already learned how to configure the Keil IDE and set up the environment for programming the nuvoton microcontroller unit N76E003. It is the time to move a little bit further and use the basic GPIO interface for controlling additional hardware. If you
The manufacturing industry is one which can be highly lucrative and continuously in demand, so it is easy to see why so many entrepreneurs enter this field. While there is certainly the potential for success here, you will also find that manufacturing is a fiercely competitive industry, and it can be hard to stand out

Intro What does one do when designing a power supply? Well, build a power supply tester, of course. One of the simplest things to build is a constant current load. This will allow for testing of the endurance of the power supply, as most of the designs out there are using slow components. However, I wanted
