—An integrated buck converter that operates under low voltage environment with fast transient response is presented. The designed buck regulator employs derivative output ripple voltage for sensing current. It is targeted to be fabricated with 180nm UMC technology at 2MHz switching frequency. The response time is less than 2.2µ Sec. The regulator provides(More)
This paper presents a modified folded cascode error amplifier of low dropout (LDO) regulator and a slew-rate enhancement circuit to minimize compensation capacitance and improve transient response. The proposed error amplifier eliminates the tradeoffs between small and large slew-rate that is imposed by the tail-current in conventional error amplifier(More)
