It’s tempting to treat an op-amp as a triangular black box in a circuit diagram, but understanding its operation gives an insight into analogue electronics that’s worth having. [Mitsuru Yamada ...

Part 5 provides spec summary of the GP/R K2-W vacuum-tube op amp and discusses measurement constraints/conditions and LTspice modeled output. The K2-W vacuum-tube op ...

Every CMOS device you deal with relies on FETs for its operation and every high-quality op-amp you throw a signal at will do so through a FET input, but these FETs are buried inside the chip and ...
