Introduction to the MMBT3904 What is a Switching Transistor? A switching transistor is a semiconductor device that can be used to control the flow of electric current in a circuit. It acts as an electronic switch, allowing current to pass through when turned on and blocking current when turned off. Switching transistors are essential components…

Introduction When it comes to creating a new electronic device, having a functional prototype is crucial. A PCB Prototype allows you to test your design, identify any issues, and make necessary adjustments before mass production. In this article, we’ll explore ten ways to make a PCB prototype that meets your exact needs, as told by…

Understanding PWM Basics Before we dive into the design process, let’s first understand the fundamentals of PWM. PWM is a method of encoding analog signal levels into a digital signal by modulating the width of the pulse. The duty cycle, which is the ratio of the pulse width to the period of the signal, determines…

Introduction to Sawtooth Waves and Generators A sawtooth wave is a basic waveform that linearly increases in amplitude before sharply dropping back down. It resembles the teeth of a saw, hence the name “sawtooth”. Sawtooth waves contain both even and odd harmonics, giving them a brighter and buzzier sound compared to pure sine waves. Sawtooth…
