ABSTRACT:
An arrangement and a method in an integrated circuit for tuning and setting a value comprising a comparator circuit having a reference voltage input and a variable voltage input is provided to produce a digital value on an output depending on a comparison between the reference voltage and the variable voltage. A first clocked counter circuit is connected to the comparator to increase or decrease the value of the first clocked counter depending on the digital value supplied from the comparator. The arrangement further comprises a second clocked counter circuit connected to the comparator to increase the value of the second clocked counter for each change of value of the comparator, and a locking circuit connected to the second clocked counter circuit to lock the value stored in the first clocked counter circuit from further changes when the second clocked counter reaches a first threshold value.
