Abstract
A circuit adjustable after packaging includes a functional circuit supplied with a power potential and a reference potential and has at least one parameter adjustable by programming at least one programmable element and a circuit to program the programmable element of the functional circuit. The adjustable circuit also includes a limiter circuit to limit the voltage between the power supply potential and the reference potential to an adjustable limiting voltage, and a circuit to adjust the limiting voltage. After adjusting a parameter of the functional circuit, the limiting voltage of the limiter circuit is adjusted.
