It has long been known that the simple combination of a depletion-mode MOSFET (and before these were available, a JFET) and a resistor made a simple, serviceable current source such as that seen on ...

An interesting analog design problem is the precision current source. Many good designs are available, but most are the three-wire types that can be used as a positive (see Figure 1) or a negative ...

Performance specs can be trumped, but elegance persists. Consider the most basic task in industrial control: driving sensors and bridges. It doesn’t matter if you’re dealing with a strain-gauge bridge ...

Traditionally, the packaged integrated circuit (IC) has been much larger than the IC itself because standard packages must also contain the lead-frame and bond wires. That wasn’t an issue for decades ...
