Reverse Polarity Protection Circuit Using P-Channel MOSFET You’ve just finished assembling an electronic project and are ready to power it up, only to realize the battery might be connected backwards. In an instant, a simple mistake can destroy hours of work. Reverse polarity is one of the most common causes of circuit failure, from hobby projects to industrial systems. The good news is that a well-designed reverse polarity… |

Design Techniques for Reducing EMI in SMPS Circuits In my previous article on EMI, we examined how the intentional/unintentional nature of EMI sources and how they affect the performance of other Electrical/Electronic devices (victims) around them. The article was followed by another one on Electro Magnetic Compatibility (EMC) which provided insights into the dangers of EMI and offered some context to how poor EMI… |

Superheterodyne AM Receiver - Working with Block Diagram and Schematics A superheterodyne receiver uses signal mixing to convert the input radio signal into a steady intermediate frequency (IF) that can be worked with more easily than the original radio signal, which has a different frequency, depending on the broadcasting station. The IF signal is then amplified by a strip of IF amplifiers and then fed into a detector that outputs the audio… |

Emergency Light An emergency light is an integral part of household electronics nowadays. We all know an Emergency light is used during a power failure to light up the home. As it is used during a power failure, it should last long, hence generally bright white LEDs are used in emergency lights, because they produce more light and consume less power. Emergency light is a very useful… |
