An amplifier has a function to increase an input signal by amplification factor of amplifier for outputting. Electric / Electronic circuit uses voltage and current in the main for input signal and ...

Today’s circuit designers usually will need to design with analog circuitry on their boards, even if the core circuitry is Processor-based or a power supply design, MEMS/sensor or such. The problem is ...

Here are two PDF files from the National Semiconductor Web Site that contain good tutorials on the fundamentals of Op Amp circuits and some of the basic analog building blocks that they can provide.

If you’ve ever wondered why an op amp has the little plus and minus symbols on it, its because at the heart of it, the device is a differential amplifier. The problem is that — ideally, at least — it ...
