Abstract
Methods and apparatuses are provided for self-trimming of a semiconductor device. An example self-trimming circuit includes a control circuit configured to, during a self-trimming operation, decode a test command signal to set a target voltage and set a voltage trim code to an initial value, and to adjust a value of the voltage trim code based on a stop signal. The example self-trimming circuit further includes a reference voltage regulator configured to receive the voltage trim code and to convert a band-gap reference voltage to an output voltage based on the voltage trim code, and a comparator configured to compare the target voltage with the output voltage and to provide the stop signal having a value based on the comparison.
