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 ...
Recently, frequent Design Idea (DI) author Christopher Paul showcased an innovative and high performance true-two-wire current source using a depletion mode MOSFET as the pass device in “A precision, ...
The Large Helical Device (LHD) and the heavy ion beam probe (HIBP) system. The inset on the left shows an enlarged view of the section from the negative ion source to the injection side of the tandem ...
