Learning the Basics: Norton’s & Thevenin’s Theorem

When building or designing an electronic circuit, we may need to simplify the circuit into an equivalent or analogous circuit consisting of only a few essential components. To achieve that, we can apply Norton’s theorem or Thevenin’s theorem to the circuit. Where the former simplifies the circuit into an equivalent current source and an equivalent … Read more

LM358 Low-Power Dual OP-AMPs Features and Circuits

One day, I asked my friend, who is an electrical appliance mechanic, “What is the most common OP-AMP you’ve seen?” He said it is the LM358; it is shaped like a 741, while overall being better. Inside the LM358 are two independent operational amplifiers that share a voltage supply. It has a maximum frequency response … Read more
