A voltage reference is dynamically and digitally controlled by a digital function. The digital function may be implemented as a digital calculation or look up table. Inputs to the function include a modifiable trim value stored in a trim register, and a substrate temperature value. The preset value of the trim register is a trim preset value generated by cutting fuses and/or leaving fuses uncut. The cutting may be performed using laser trimming-devices. The output of the digital function is a corrected reference trim value that controls the gain of a vol...
1. A method for digitally controlling a voltage reference, the method comprising:obtaining an original voltage reference; generating a trim preset value by performing an initial trimming of the original voltage reference; generating an intermediate trim value based on the preset trim value; generating a corrected reference trim value, based on the intermediate trim value and a substrate temperature value; and setting a gain for a voltage reference amplifier, based on the corrected reference trim value; wherein said generating the corrected reference trim...
