Trimming circuit and method applied to voltage generator
A trimming method for a voltage generator is provided. The voltage generator generates an output voltage according to a reference voltage. The trimming method includes the following steps. Firstly, in a step (a), an initial value of a trimming code is provided. Then, in a step (b), the reference voltage is generated to the voltage generator according to the trimming code, so that the output voltage is correspondingly generated by the voltage generator. Then, in a step (c), an average voltage of the output voltage is compared with a target voltage. If the average voltage does not reach the target voltage, the trimming code is gradually changed, and the step (b) is repeatedly done. If the average voltage reaches the target voltage, the trimming code is locked.
