    How to design discrete circuits for transistor beta changes?

    In my circuits/active devices course we had to make amplifier designs with various type of transistors (BJT, JFET, MOSFET). In each design the transistor beta parameter played an important role in deciding which resistors to use in the final amplifier circuit. This beta parameter changes widely...

    Precision hole making methods for small holes

    I'm designing a fixture for quality control and need a few precision holes. Their diameters range from 1/8" to 5/16" and need to be ±0.0002" with a depth of 1/2". I've been looking into EDM hole making and honing, but neither seem to be great for that range of diameters. Anyone know of any other...
