  • PMOS and NMOS Transistors

    Microprocessors are built of transistors. In particular, they are constructed out of MOS transistors. MOS is an acronym for Metal-Oxide Semiconductor. There are two types of MOS transistors: pMOS (positive-MOS) and nMOS (negative-MOS). Every pMOS and nMOS comes equipped with three main component

  • Choosing a Current-Limiting Resistor

    Introduction Current-limiting resistors are placed in a circuit to ensure that the amount of current that flows does not exceed what the circuit can safely handle. When current flows through a resistor, there is, in accordance with Ohm's Law, a corresponding voltage drop across the

  • Forward Bias vs. Reverse Bias and their Effects on Diode Functionality

    Since the day my mother surprised me with the first home computer for Christmas back in, well, let's just say a long time ago, I've been intrigued by the technology. Anyway, at the time, I was the envy of every fellow geek, nerd, and teacher at my school. There I was with an

  • Over-voltage Protection for Power Supplies

    Power supply over-voltage protection is really useful - some PSU failures can put damaging large voltages on the equipment. Over-voltage protection prevents this happening on both linear regulators and switch mode power supplies. Although modern power supplies are now very

  • What Is Spike/Surge Protector And Power-Line Filter?

    A surge protector or surge suppressor is a device designed to protect electrical devices from undesirable sudden and short-term increase in voltage spike. Both voltage surge and voltage spike referring to short-term increase in voltage look similar but are different. While a volt

  • BASIC ANALOG POWER SUPPLY DESIGN

    There's the old saying: “You can give a man a fish and he will eat for a day or you can teach a man to fish and he will eat forever.” There are many articles that give the reader a specific design for building a power supply, and there's nothing wrong with these cookbook designs.

  • Frequency Response Analyzer Introduction

    What is a Frequency Response Analyzer? Find a Local Distributor A Frequency Response Analyzer (FRA) is a high precision measurement instrument used to analyze components, circuits and systems (known as devices under test, or DUT’s) in the frequency domain. An FRA typically generates a sinusoida
