Abstract
Techniques to perform bandgap circuit trimming that maximize the operating range and minimize the trimming time at which the bandgap will be accurate. A bandgap circuit output voltage may be trimmed by heating the circuit, supplying increasing input power to the bandgap circuit, and adjusting operational parameters of the bandgap circuit to generate a constant bandgap circuit output voltage. When the bandgap circuit output voltage may remain constant, a constant input power may be applied to the bandgap circuit and its output voltage may be adjusted to a predetermined voltage level.
