  2. Fig. 1. Structure of LDO with the proposed analog driver.

  3. Fig. 2. Conceptual block diagram of the analog driver.

  4. Fig. 3. Circuit diagram of the SRE circuit used in the current-mirror amplifier.

  5. CONCLUSION • The proposed analog driver can also extend to other large-capacitive-load applications such as column buffers in flat-panel displays and switched-capacitor power converters for performance enhancements.
