Abstract
A circuit is described for trimming a monolithic PN junction isolated silicon IC. The value of a moderate value resistance network is translated to a current that can be made to have a predetermined temperature coefficient and can be applied to the IC. A voltage regulator is shown in which the output voltage and the temperature coefficient can be independently adjusted both at wafer sort and after assembly.
