Abstract:
A new security switch called "e-fuse" is presented here. It acts as a fuse in the bias feed, providing very fast switch-off times, thus protecting the device under test and the measurement equipment such as probe tips. It can be applied to FET-type transistors as well as to bipolar ones, including HBTs.
