An Optimization Method for LDO Design Based on ANN Algorithm

In order to solve the issues of long design cycles and low efficiency of integrated circuit design., a new method combining ANN algorithm was proposed to improve the comprehensive performance of LDO circuits. In this paper., the device parameters and corresponding performance of the LDO circuit were collected as a dataset to train the ANN model. When given the specific target performance of the LDO circuit., the model can predict the optimal device parameters corresponding to the performance., achieving the synchronous improvement of the four key parameters of PM, UGBW., PSRR., and I
Q
. The results show that the R
²
of the ANN model can be as high as 0.982. Therefore., the proposed method in this paper can effectively accelerate the design of LDO and improve its comprehensive performance.
