Abstract

An integrated circuit has a circuit part and a trimmable resistor, the resistance whereof may be modified by Joule effect. The trimmable resistor has first and second connection terminals coupled to the circuit part, and an intermediate terminal that divides the trimmable resistor into two portions. The first and the second connection terminals and the intermediate terminal are coupled to respective pads configured to receive electrical quantities designed to cause, in use, a respective trimming current flow in each portion. In this way, a substantially zero voltage drop is maintained between the first and second connection terminals while current is flowing in the resistor to change an electrical characteristic of the resistor, such as resistance or thermal coefficient.
