Abstract:

A new two-way trimming circuit for CMOS bandgap reference is presented in this paper.With the sample and practical trimming method to achieve high-precision adjustment,the proposed method utilizing sink and source current to actualize fine and coarse adjustment,and not affect the temperature characteristic of the bandgap.Consequently,the purpose of adjusting the reference voltage accuracy is realized.

Key words: bandgap reference;trimming;analog circuits
