Electrically Programmable Fuses for Analog and Mixed Signal Applications in Silicon Germanium BiCMOS Technologies

An electrically programmable fuse, known as "eFUSE," is used to provide passive device trimming and circuitry fine tuning for analog and mixed signal applications in silicon germanium BiCMOS technologies will be discussed. Timing analysis, pre-and post-programming electrical characterization, and electro-migration failure analysis will be presented.
