Paulo shared an Excel-based transistor amplifier calculator. ‘Besides the basic gain and biasing calculations many others implement, this calculator can also estimate noise which is a bit more involved’:
..Because this is a circuit I use frequently, I decided to make an Excel spreadsheet to ease the calculations. The spreadsheet started as a simple resistor value calculator (given a bias point) and later evolved to include some more advanced features such as noise estimation. I decided to share this spreadsheet in this article in hopes it will help other Electronics enthusiasts in these same tasks..
