Abstract
A method and an apparatus for calibrating an integrated circuit by blowing a fusible link. A blowing current is caused to flow through the fusible link via a switch element. When the fusible link blows to render it nonconductive, a sudden voltage pulse appears which is detected by a differentiating element and utilized to quickly turn off the switch element and, thereby, avoid damage to the integrated circuit.
