Abstract
This letter describes a H/V linear regulator for enhancing power supply rejection (PSR) for generating the program/erase voltage. In order to reduce the ripple voltage of the H/V linear regulator, using an additional feedback technique is proposed. The proposed H/V linear regulator has dual loop feedback that improves loop gain and PSR. In the simulated PSR performance, -43.1 dB is observed with the proposed H/V linear regulator at 2.12MHz. This result is 13 dB better than results obtained with the conventional H/V Linear regulator.
