Abstract
There is described a method to change the value of a thermally-trimmable resistor in a non-permanent way by raising the temperature of the thermally-trimmable resistor to a level that is somewhere between room temperature and trimming temperature. By doing this, the trimming range that is available via true thermal trimming may be explored without actually trimming the value of the resistor. This is possible when the thermally-trimmable resistor, or a portion thereof, has an essentially non-zero temperature coefficient of resistance (TCR).
