MOSFET Current Mirror Circuits: A Simple Guide for Beginners
The Problem : A MOSFET current mirror is a circuit used to copy (mirror) a current from one branch to another, ensuring consistent current flow in different sections of a circuit. This is crucial in amplifiers and sensor circuits where stable current is essential. However, beginners often face issues with incorrect resistor values or …

SMPS Over-Power Protection Guide: A Beginner’s Solution
Switch Mode Power Supplies (SMPS) are commonly used to power electronic circuits, but they can get damaged if overloaded. Over-power protection (OPP) prevents this by limiting the power drawn by the load, ensuring the SMPS operates within safe limits. Without OPP, excessive power can lead to overheating, damage, or even component failure. The Problem …
