OLED Soldering Controller When soldering, sometimes the need arises to control the temperature of the soldering iron, especially, for micro soldering or any other precision soldering job. It is important to keep the temperature under control because overheating may damage sensitive semiconductor parts. That is where a temperature-controlled soldering station comes to play. But the problem is… |

How Does Successive Approximation (SAR) ADC Work and Where is It Best Used? An Analog to Digital Converter (ADC) is a type of device that helps process real-world analog signals for digital systems. To understand real-world data like temperature, humidity, pressure, and position, we need transducers that convert these measurements into electrical signals. Since the majority of devices we use at the moment are digital, this conversion becomes… |

Designing NOT Gate using Transistors An Integrated Circuit or IC is a combination of many small circuits in a small package that together performs a common task. For example, 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… |

Bi-Directional Logic Level converter using MOSFET Back in the ENIAC era, computers were more analog in nature and used very few digital ICs. Today an average Joe’s computer works with multiple voltage levels, people who had seen the SMPS of a CPU would have noticed that your computer requires ±12V, +5V and +3.3V to operate. These voltage levels are very important for a computer; a specific voltage determines the state of… |
