An SCR topology transmogrifies into BJT two-wire precision current source with a self-resetting fault-current limiter.

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 ...

Author Mazi Hosseini describes a simple, low-cost, voltage-controlled current source using two op amps that provides a good range of current and maximum load. One challenge in circuit design is ...

Researchers report a new, two-dimensional transistor made of graphene and molybdenum disulfide that needs less voltage and can handle more current than today's semiconductors. University at Buffalo ...

Researchers have revived and improved a once-reliable technique to identify and count defects in transistors, the building blocks of modern electronic devices such as smartphones and computers.
