Abstract

This paper presents a capacitor-less low drop-out (LDO) regulator with current mode transconductance amplifier & slew-rate enhancement circuit. The proposed current mode transconductance amplifier as error amplifier improves the slew rate & slew- rate enhancement circuit further senses the transient voltage at the output of the LDO to increase the bias current of the error amplifier for a short duration. Hence, transient response of LDO has been further improved using these techniques. The proposed LDO regulator will be designed and simulated in 180nm CMOS technology.
