The present invention relates to an arrangement and a method in an integrated circuit for tuning and setting a value comprising a comparator circuit (101) having a reference voltage input and a variable voltage input and being provided to produce a digital value on an output depending on a comparison between the reference voltage (102) and the variable voltage (104). A first clocked counter circuit (105) is connected to the comparator and provided to increase or decrease the value of the first clocked counter (105) depending on the digital value supplied from the comparator (101). The arrangement further comprises a second clocked counter circuit (106) connected to said comparator (101) and being provided to increase the value of said second clocked counter for each change of value of said comparator (101), and a locking circuit (106) connected to said second clocked counter circuit (106) and provided to lock the value stored in said first clocked counter circuit (105) from further changes when said second clocked counter reaches a first threshold value. |
